San Galgano Abbey is Italy's most famous example of roofless Cistercian architecture, and it preserves, just a few hundred metres away, the real sword in the stone: the one that a young Tuscan knight, San Galgano Guidotti, drove into a travertine boulder in December 1180 as a gesture of renunciation of military life. Two distinct sites: the great abbey in French Gothic style at the bottom of the valley and the Chapel of Montesiepi on the hill above: form one of the most layered spiritual complexes in Tuscany, today managed by the Fondazione San Galgano and open every day of the year.
Behind the touristy postcard of the nave open to the sky lies a history documented in Sienese notarial archives, Cistercian registers and papal bulls: seven centuries of splendour, decline, plagues, mercenaries, lightning and abandonments. The Italian search numbers give the measure of the phenomenon: 33,100 monthly searches for "abbazia di san galgano", 22,200 for "san galgano", 6,600 for "spada nella roccia san galgano". A huge market of historical and tourist curiosity, fuelled also by the Arthurian fascination of the sword and the images of Andrei Tarkovsky, who shot the final scene of Nostalghia (1983) there.
This guide reconstructs 850 years of history of the abbey and the hermitage, separates legend from facts established by the metallurgical analyses of the University of Pavia (2001), explains how to visit the two sites today, and why Mario Moiraghi argues that the model of King Arthur's sword in the stone is precisely our Tuscan knight.
Where is San Galgano Abbey: geography of the Val di Merse
San Galgano Abbey stands at coordinates 43.149504 N, 11.155202 E, in the frazione of San Galgano in the municipality of Chiusdino, in the province of Siena, southern Tuscany. It lies along the provincial road 73 bis that connects Siena to Massa Marittima, at a point in the Val di Merse where the valley opens into a basin of flat meadows surrounded by woods of holm oaks, Turkey oaks and chestnut trees.
Distances from the main Tuscan centres: Siena 33 km to the south-west (40 min via SS73), Grosseto 60 km (1 h 10), Florence 110 km (1 h 50 via A1), Rome 230 km (2 h 50), Volterra 60 km (1 h 15 via the Colline Metallifere).
The Val di Merse is one of the best-preserved areas in Italy from a naturalistic point of view. It takes its name from the Merse river, a right tributary of the Ombrone, and extends over about 600 km² between Chiusdino, Monticiano, Murlo, Sovicille and Casole d'Elsa: land of medieval villages, free thermal baths (Bagni di Petriolo), woods protected by the Basso Merse Nature Reserve, pit-aged pecorino cheese and cinta senese pork.
The Hermitage of Montesiepi, where the real sword in the stone is located, stands one kilometre south-west of the abbey, on the summit of a small hill at 316 metres above sea level. It is reachable on foot in 15 minutes along a well-marked path starting from the abbey's car park, or in 3 minutes by car following signs for "Eremo di Montesiepi". The two sites form a unique complex: first the circular chapel where San Galgano lived the last year of his life and where he is buried, then the great Cistercian abbey built a century later to accommodate the flow of pilgrims.
San Galgano Guidotti: the nobleman who became a hermit (1148-1181)
The story begins with a man, not with an abbey. Galgano Guidotti was born in Chiusdino between 1148 and 1152 (hagiographic sources differ by a few years) into a family of the minor feudal nobility of the Val di Merse. His father, Guidotto, owned a castle and some estates near the village. His mother, Dionisia, raised him in a chivalric environment of hunting parties, tournaments and weapons.
The oldest source on his life is the Vita beati Galgani, written a few years after his death by an anonymous Cistercian monk and preserved in the archives of the Curia of Volterra. The document tells of a dissolute youth marked by violence, libertinism, scant respect for religion: a typical medieval knight of the period, in practice, who fought in the wars between Siena and its neighbours and squandered his family's patrimony.
The conversion: the dream and the apparition of the Archangel Michael
The turning point arrived around 1180, when Galgano was about thirty. According to the hagiographic tradition, one winter night the Archangel Michael appeared to him in a dream, leading him onto a hill and showing him the summit of a mountain where twelve apostles welcomed him beside a round church. For some weeks the knight resisted: he even tried to marry a noblewoman of Civitella Marittima to bring order back to his life. But on the way to the wedding, his horse refused to proceed and led him, of its own accord, all the way to the summit of the Montesiepi hill: exactly the hill seen in the dream.
The gesture of the sword driven into the rock (December 1180)
To seal the conversion with an irreversible symbolic act, Galgano drew his knight's sword and tried to break it against a stone to plant the pieces in the ground in the shape of a cross. But the blade, instead of breaking, penetrated the rock as if it were butter, stopping only at the level of the hilt. The cruciform shape was perfect: horizontal grip, vertical blade planted in the boulder: and it instantly became his first cross of prayer.
The episode, dated by the sources to December 1180, is the historical-legendary core of the whole affair. Whether or not it is a hagiographic reinterpretation of a real gesture, the sword is indeed there: planted in a boulder of travertine and ophiolite, preserved today under a plexiglass case at the centre of the Montesiepi Rotunda, with a protrusion of about 25 cm of hilt and grip above the rock surface.
Galgano lived his single year as a hermit in a hut on the hill, feeding on roots and herbs, receiving a few visits from pilgrims drawn by his reputation for holiness. He died on 30 November 1181 at little more than thirty years old. Four years later, on 5 December 1185, Pope Lucius III signed the bull of canonisation: an exceptionally brief time by 12th-century ecclesiastical standards, and one of the fastest canonisation processes in Church history.
The sword in the stone: legend or history?
For over eight centuries, the sword in the stone of San Galgano was interpreted as pure hagiographic legend: a symbol of conversion, a reinterpretation of the Christian iconography of the sword-cross, a narrative detail constructed a posteriori to enrich the Vita beati Galgani. Even 19th- and 20th-century pilgrims who climbed up to Montesiepi saw the sword as a late reproduction, perhaps medieval but not dating back to 1180, placed in the boulder as an ex-voto by some anonymous 14th-century devotee.
This "rationalist" interpretation was spectacularly overturned in 2001 by a series of scientific analyses that changed the debate forever.
The University of Pavia study (2001)
In early 2001, the Associazione Culturale Progetto Galgano and the Department of Organic Chemistry of the University of Pavia launched a campaign of analyses on the sword, coordinated by Professor Luigi Garlaschelli (an organic chemist also known as a consultant for CICAP), with researchers from the Universities of Pavia, Milan, Padua and Siena as well as technicians from the CNR. The aim was threefold: to date the blade, to verify whether it really crosses the boulder, to analyse the metallurgical composition.
The results, presented at the Chiusdino conference of 20-21 September 2001 and published in the proceedings of the University of Florence, are unequivocal:
1. Dating: the analysis of iron impurities (carbon, manganese, phosphorus, sulphur) places the manufacture of the blade between the late 12th and early 13th century, compatible with the 1180 of the legend. 2. Style: the form of the one-handed sword, with simple cruciform hilt, discoidal pommel and blade 5-6 cm wide, is typical of Romanesque-Gothic knight's swords of the second half of the 13th century. 3. Integrity: georadar and magnetic induction techniques confirm that the sword effectively penetrates the boulder by 12-15 cm below the visible surface, with no signs of recent tampering. 4. The rock: a single block of travertine with ophiolite inclusions, compatible with the soils of the Val di Merse.
In other words: the sword in the stone is authentic 12th-century and really driven into the rock. What remains historically undecidable is who put it there: whether the hand of Galgano Guidotti, the monks a few years after his death, or a later addition (13th century) as a symbolic relic. But the coherent dating is in itself an extraordinary blow for the credibility of the legend.
The mummified hands
A collateral discovery of the 2001 investigations also concerned the two mummified hands preserved in a case in the Montesiepi chapel: traditionally attributed to a thief who, according to legend, had tried to steal the sword and was torn apart by wolves as divine punishment. Radiocarbon dating places them between the 12th and 13th centuries, also consistent with the Galganian context, although the attribution of the theft remains unprovable.
The Cistercian abbey: French masters and Gothic in Tuscany (1218-1288)
After the canonisation of Galgano in 1185, the flow of pilgrims to Montesiepi grew rapidly. As early as 1185-1190, the episcopal curia of Volterra had a first circular chapel of Romanesque plan built next to the saint's tomb: the Montesiepi Rotunda that we still see today: to house the sword and guard the sepulchre.
But the hilltop hermitage complex was too small to manage the growing pilgrims. In 1201, Ugo, bishop of Volterra, decided to summon the Cistercian monks to Montesiepi. The choice of order was not random: the Cistercians, founded at Cîteaux in 1098, were the great monastic novelty of the century, custodians of an austere spirituality, managers of an effective European economic network, and able to build Gothic churches of the highest technical level.
The arrival of the monks from Casamari
The first Cistercians arrived in Montesiepi in 1218: not directly from Cîteaux, but from the Abbey of Casamari (Frosinone, southern Lazio), then the main Cistercian mother-monastery of central-southern Italy. Casamari had just completed its great Gothic church (1217) and the Tuscan monks arrived with the fresh architectural know-how in their pockets. The designer was probably donnus Johannes (Don Giovanni), monk-architect who had directed the final works at Casamari. His hand is recognisable in the proportional rigour of the naves, in the French Gothic (rib vaults, pointed arches, external buttresses), and in the system of cloisters to the south of the church.
The construction: 70 years of works (1218-1288)
The works began in 1218 and lasted for seventy years. Resources came from the Republic of Siena, from donations by local feudal lords (Pannocchieschi, Ardengheschi, Visconti di Campiglia), from the agricultural rents of the Cistercian estates and from the flow of pilgrims. The official consecration took place in 1268, when the bishop of Volterra Alberto Solari blessed the high altar. Finishing works continued until 1288, the year of the definitive configuration:
- ●Abbey church in Latin cross plan, 70 m long, 21 m wide, with three naves, square apse, transept and five radial chapels. Central nave about 23 m high, originally covered by a ribbed barrel vault in brick.
- ●Main cloister to the south of the church, 31 × 27 m, with a double-order portico and central cistern.
- ●Chapter house, refectory, dormitory of the lay brothers and kitchens arranged around the cloister.
- ●Bell tower in masonry, about 36 m high, at the crossing of the transept.
San Galgano Abbey is the first great Gothic church in Tuscany and one of the first in all of central Italy. It anticipates by more than a century the great Gothic cathedrals of Florence (Santa Croce, 1294-1442), Siena (1215-1348), Orvieto (1290-1591). Its French model would be fundamental for the birth of the Sienese Gothic school of the 14th century.
The apogee of the 13th-14th century
Between 1288 and 1330 the abbey lived its golden age. The monastic community averaged 40-60 choir monks plus as many lay brothers (monk-workers of the fields). The Cistercian estates in the Val di Merse and the Maremma produced wheat, wine, oil, wool, sheep's cheese and timber: an efficient rural economy that made the abbey one of the largest agricultural producers in central Tuscany. The Abbot had the rank of ecclesiastical prince, with the right of asylum and the capacity to host popes and emperors (Frederick II of Swabia stayed at San Galgano in the 1240s). In 1334-1336 the side chapel of the hermitage was frescoed by Ambrogio Lorenzetti: a cultural investment that testifies to the prosperity of the Galganian cult.
Apogee and decline: plagues, mercenaries, abandonment (14th-18th century)
Starting in the mid-14th century, a chain of catastrophes crumbled the rural empire of the abbey in a few decades.
The famine of 1328 and the plague of 1348
The great famine of 1328 struck Tuscany hard: the monks of San Galgano managed to survive thanks to grain reserves but had to reduce monastic numbers. Twenty years later, the Black Death of 1348 decimated the community: according to the abbey's records, only eight monks survived out of the original fifty. The demographic effect was devastating and never fully recovered.
The incursions of Giovanni Acuto and the mercenaries (1363-1400)
The second half of the 14th century in Tuscany was dominated by the companies of fortune: mercenary armies, often coming from northern Europe, who crossed the region selling themselves to the highest bidder. San Galgano Abbey, rich and isolated, was a natural target for raids.
The most famous case is that of the English condottiero John Hawkwood: in Italian Giovanni Acuto (c. 1320 - 1394): captain of the infamous White Company. Hawkwood sacked the abbey on two distinct occasions documented by the Sienese archives (1363 and around 1380), with thefts of livestock, wine, liturgical gold, sacred vestments and bell bronzes. On one of the two occasions, the mercenaries imprisoned the abbot demanding a ransom. Other companies (San Giorgio, della Stella, Hungarian and German mercenaries) passed through in the same decades: for forty years the abbey was effectively no man's land.
The transfer to Siena (1474)
Economic and security conditions deteriorated to the point that, in 1474, the surviving monks decided to definitively abandon the abbey complex and move into the heart of Siena, where they built the so-called Palazzo di San Galgano (today the seat of the Rectorate of the University). The original abbey remained entrusted to a few lay brothers who managed the remaining estates, while the church was officiated only on major liturgical feasts. For the rest of the 15th and 16th centuries, San Galgano survived in slow twilight: the abbots were often commendatory (nobles who received the title without ever residing on site), the rents were diverted elsewhere, the barrel vaults developed structural cracks.
The silent ruin (16th-18th century)
In 1576, a pastoral visit by the bishop of Volterra found the church "in very bad condition", with the roof partly collapsed on the right side aisle. In 1652, a decree of Pope Innocent X suppressed all monasteries with fewer than six resident monks: San Galgano, reduced to a couple of elderly religious, was formally demoted to the rank of dependent priory of the diocese of Volterra. By 1700 there was no longer any resident monk: the abbey was a great cathedral awaiting its final collapse, guarded only by a lay chaplain in the former guest house.
The collapse of 1781: the lightning strike on the bell tower
The precise dates of the final structural collapse of the abbey are the subject of a small debate among local historians. The chronology accepted by the Fondazione San Galgano and by the Soprintendenza is the following:
- ●In 1781, the last barrel vaults of the central nave, already unsteady, gave way suddenly during a night of autumn storm, leaving the church completely open to the sky: the famous "roofless church" that we know today.
- ●In 1786, a lightning bolt struck the bell tower during a summer thunderstorm. The tower, already weakened by decades of abandonment, split vertically and collapsed in on itself. The great 14th-century bell, miraculously surviving, was recovered but then melted down and sold as scrap bronze.
- ●In 1789, the bishop of Volterra signed the decree of formal deconsecration of the church.
The Leopoldine reforms of Peter Leopold of Lorraine contributed to the final destiny: the suppression of numerous convents (1782-1786) within the framework of the Josephinist policy of ecclesiastical reorganisation made San Galgano a work devoid of institutional sense. In the following years, the conventual buildings were transformed into a cast-iron foundry and the cloister spaces into a rural farmhouse. For over a century (1789-1924) the abbey remained in semi-rural abandonment: peasants brought livestock into the church during the rainy months, the paving stones were removed, ivy covered the external buttresses. The first photographs of the early 20th century show it completely invaded by vegetation, in an aesthetic of "picturesque ruin" that would later become one of its great tourist arguments.
The Chierici restoration (1924-1926)
The awakening came in 1924, when the Ministry of Public Education commissioned the architect Gino Chierici, Superintendent of Monuments of Siena, to lead a conservative restoration. Chierici was an exponent of the philological restoration school inspired by the principles of John Ruskin and Camillo Boito: no fantasy reconstructions, only consolidation of residual structures, removal of rural superfetations (stables, 18th-century barns), filling of gaps with materials distinguishable from the original.
The works, lasting from 1924 to 1926, restored to the complex the monumental legibility that we admire today. The naves were freed from vegetation, the external walls consolidated, the buttresses stabilised, the main cloister partially reconstructed. Subsequent minor restorations followed in 1969, 1989, 2003 and 2018. Current management is entrusted to the Fondazione San Galgano, established in 2007.
The Chapel of Montesiepi: rotunda with the authentic sword
About one kilometre south-west of the abbey, on the summit of the hill where San Galgano lived his single year as a hermit, stands the Chapel of San Galgano at Montesiepi, more commonly known as the Hermitage of Montesiepi or Rotunda of Montesiepi. It is the true mystical heart of the Galganian complex, and it preserves the original sword in the stone.
Architecture: the Romanesque rotunda of 1182-1185
The chapel was built between 1182 and 1185, immediately after the saint's death (1181) and even before his formal canonisation. The patron was probably the bishop of Volterra Ugone Saladini, in agreement with the Guidotti family and the free commune of Chiusdino. It is therefore the oldest Christian structure of the entire complex.
The most surprising feature is the circular plan, unusual for the era and of clear early Christian and Byzantine inspiration: the models are the imperial Roman mausoleums (Santa Costanza, San Vitale in Ravenna) and the Middle Eastern martyria (Holy Sepulchre, Dome of the Rock). Contained dimensions: interior diameter of 10 metres, height at the dome of 12 metres, walls in local sandstone over a metre thick. The interior is dominated by an extraordinary truncated-cone dome made of concentric rings alternating red brick and white travertine: a hypnotic optical effect when looking upwards. At the centre of the floor, under a plexiglass case, the original sword in the stone of 1180.
The side chapel and the Lorenzetti frescoes
Between the late 13th century and the early 14th, a rectangular chapel (about 8 × 6 metres) in Cistercian Gothic style was added to the south-east flank of the rotunda, housing the celebrated frescoes of Ambrogio Lorenzetti (1334-1336). The exterior of the rotunda is articulated by a covered portico of four bays, reconstructed in the 15th century.
The frescoes of Ambrogio Lorenzetti (1334-1336)
The frescoes of Ambrogio Lorenzetti are considered one of the absolute peaks of 14th-century Sienese painting, among the master's most important works alongside the cycle of the Good Government in the Palazzo Pubblico of Siena (1338-1339). The fact that they are here, in an isolated chapel in the middle of the Val di Merse, is one of the small miracles of Italian art history.
The cycle is articulated on three walls and in the vault. On the back wall, a monumental Madonna in Majesty with saints and musical angels, and below, in an iconographically dense position, a figure of Eve carrying a goatskin on her shoulders (lust) and a fig in her hand (original sin). On the same wall, below, an Annunciation where Lorenzetti uses the real window of the chapel as a perspectival element: a virtuosity that anticipates Masaccio and Piero della Francesca by a century. On the left wall, a unique scene in Tuscan Marian iconography: San Galgano on his knees offering the Virgin a sculpted model of the rock with the sword driven in, alongside a symbolic View of Rome with towers and domes. In the vault, six tondos of Prophets of the Old Testament, today seriously deteriorated.
In 1967 the frescoes were detached from the walls with the strappo technique to be restored in Florence, during the great post-flood operations. The sinopie (preparatory drawings) were brought to light and are today exhibited next to the original frescoes, repositioned in 1989.
Parallels with the Arthurian legend: Mario Moiraghi's thesis
One of the most fascinating questions linked to the sword in the stone of San Galgano is its relationship with the legend of King Arthur. The question is simple but vertiginous: who copied from whom? Galgano's sword from 1180 predates all the great Arthurian texts that speak of a sword driven into the rock: Lancelot-Grail (1215-1230), Estoire del Saint Graal (1220), the Vulgate Cycle (1220-1240). Could the model of the Arthurian sword be precisely that of our Tuscan knight?
Mario Moiraghi's book (2003)
Supporting this thesis with a wealth of documents is the historian of medieval culture Mario Moiraghi, who in 2003 published with Àncora editions the volume "L'enigma di San Galgano: la spada nella roccia tra storia e mito". The book, the fruit of years of research in the archives of Siena, Volterra, Pavia and Cîteaux, proposes a strong thesis: the story of Galgano Guidotti, widely diffused in European Cistercian circles already in the years 1185-1200, was a direct source of inspiration for the Arthurian novelists of the first half of the 13th century.
Moiraghi's arguments are of three kinds:
1. Chronological. Galgano's sword is documented at least from 1185 (canonisation). The first Arthurian texts speaking of a sword in the rock (Suite du Merlin by Robert de Boron, 1200-1210) are 15-25 years later. The direction of the narrative flow, at least for this reason, must therefore be from Italy towards France. 2. Toponymic. The name "Galgano" shows an extraordinary similarity with Galvano (in English Gawain), King Arthur's most valiant knight. Geoffrey of Monmouth in the Historia Regum Britanniae (c. 1136) latinises him as Walganus; in medieval Italian variants he becomes Galvano. Moiraghi argues that the phonetic proximity Galvano-Galgano reflects an oral circulation of the name. 3. Iconographic. Several elements of the life of San Galgano (dream of the Archangel, mystical call, conversion, hermit retreat, sanctity achieved in solitude) trace the scheme of the Grail quest. The story of Parsifal and that of Galahad both have close structural analogies with the affair of Galgano Guidotti.
Moiraghi's thesis is not universally accepted: the debate remains open, and other scholars prefer to explain the analogies as parallel products of a common medieval symbolic substratum. But the chronological advantage of Galgano's sword remains a fact difficult to ignore. It is also worth remembering that the Cistercian monks constituted a transcontinental intellectual network that circulated manuscripts, legends and iconographic motifs with great rapidity: it is perfectly plausible that the life of San Galgano, copied in the scriptoria of Cîteaux, Clairvaux, Casamari and Pontigny, reached the ears of Chrétien de Troyes or Robert de Boron contributing to the elaboration of the Arthurian epics in the langue d'oïl.
San Galgano in cinema: Tarkovsky and beyond
San Galgano Abbey is one of the most cinematographic places in Italy: its nave open to the sky, the Gothic arches silhouetted against the Tuscan serenity, the green grass growing where the floor should be, the dreamlike and contemplative atmosphere: all this has made it, from the 1980s onwards, a recurring location for European auteur cinema.
Andrei Tarkovsky: "Nostalghia" (1983)
The film that consecrated the abbey in the world cinematographic imagination is Nostalghia (1983) by the Russian director Andrei Tarkovsky. It is the first film by Tarkovsky made outside the USSR, during an Italian sojourn (1982-1983) that would turn into a definitive exile: the director would never return to his homeland, and would die in Paris in 1986.
Nostalghia is the journey of the Russian writer Andrei Gorchakov (Oleg Yankovsky) across Tuscany and Lazio in the company of the Italian translator Eugenia (Domiziana Giordano). The Tuscan locations include Bagno Vignoni, the Val d'Orcia, and San Galgano Abbey.
The final scene: one of the most meditative sequences of 20th-century European cinema: is shot under the buttresses of the abbey. Gorchakov sits on the lawn next to a dog in the foreground. Behind him, the camera reveals: in a rear projection effect combined with superimposed sets: the Russian dacha of his childhood, as if two landscapes and two times had overlapped forever. The Gothic ruin becomes the frame of a universal nostalgia: the roofless church as symbol of the absence that runs through the film. Tarkovsky saw in it the visual concretisation of his cinema: the ruin as architecture of time, the nave open to the sky as a metaphor for the spirit exposed to the elements.
Other cinematographic appearances
After Nostalghia, San Galgano became a recurring location of Italian and international cinema: *The English Patient (Anthony Minghella, 1996, winner of 9 Academy Awards), Maraviglioso Boccaccio by the Taviani brothers (2015), The Young Karl Marx (Raoul Peck, 2017), and more recently La chimera* by Alice Rohrwacher (2023), where the dreamlike scenes of the Etruscan tomb are shot precisely under the Gothic vaults.
The abbey also hosts classical music concerts (every summer the "Aperitivi nel Chiostro" festival), high-profile civil and religious weddings (rental fees of the complex between 5,000 and 15,000 euros per event), and fashion photo shoots for magazines like Vogue Italia and Architectural Digest.
Visiting today: opening hours, tickets, FAI management and Fondazione San Galgano
In 2026, San Galgano Abbey is open to the public every day of the year (including Christmas and New Year) and is managed by the Fondazione San Galgano, a public-private body answering to the Municipality of Chiusdino, the Province of Siena and the Region of Tuscany. Important note: the abbey is not part of the FAI circuit (Fondo Ambiente Italiano), despite its monumental qualities. The confusion is frequent, but management is entirely local.
2026 opening hours
The morning opening time is always fixed at 9:00, while the evening closing varies by season:
| Period | Closing |
|---|---|
| November - March | 17:30 |
| April, May, October | 18:00 |
| June, September | 19:00 |
| July, August | 20:00 |
Last entry is allowed 15 minutes before closing time. The Chapel of Montesiepi has the same hours as the abbey, but pedestrian access to the path remains open 24h/24 (the gate of the circular chapel, however, is closed after the indicated time).
Tickets and prices
The ticket system is unique and cumulative: with a single ticket you visit both the abbey at the bottom of the valley and the Museo di San Galgano in Chiusdino (the civic museum in the village, with sculptural finds, manuscripts and devotional objects). The Chapel of Montesiepi, being a place of worship, has free and gratuitous entry during opening hours.

For information: tel. 0577-049312, e-mail abbaziasangalgano@gmail.com.
Duration of the visit
An essential visit to the abbey + Chapel of Montesiepi takes about 1 hour and 30 minutes: 40-50 minutes for the abbey (nave, cloister, chapter house), 15-20 minutes of footpath towards Montesiepi, 25-30 minutes for the rotunda (sword, Lorenzetti frescoes, panoramic view). With the Museo di San Galgano in Chiusdino included in the ticket, count 2.5-3 hours total.
Practical advice
Best period: April, May, September and October, with golden light and mild temperatures (avoid the central hours of July-August, when the grass of the nave becomes scorching). The flooring is grass and irregular cobbles: high heels not recommended. The golden hour of sunset offers the most spectacular light; drone photography is prohibited without prior authorisation from the Foundation. Picnic not allowed inside the abbey, but a good trattoria ("Le Macine") is 200 metres from the car park. Dogs admitted on a leash.
How to get to San Galgano Abbey
The abbey is located in the open countryside, 9 km from the centre of Chiusdino and 33 km from Siena. The car is by far the most convenient means, but alternatives by public transport are possible for those who don't drive.
By car
From the A1 Autostrada del Sole: from the north, exit Florence-Impruneta → Florence-Siena link → ring road → SS73 towards Massa Marittima → San Galgano junction (1 h 45 from Florence). From the south, exit Chiusi-Chianciano → SS326 → Siena ring road → SS73 (2 h 30 from Rome). From the Tyrrhenian coast: from Grosseto SS223 → exit Monticiano/San Galgano (1 h 10); from Pisa-Livorno SS1 → SP329 → SP73 (1 h 40).
Parking: large free car park with about 200 spaces just to the right of the junction. On summer weekends it can fill up by mid-morning: arrive before 10:00 or after 15:30.
By train + bus
The abbey is not reachable directly by train. The procedure is: train to Siena (from Florence 1 h 30, €12-15 one way; from Rome via Chiusi-Chianciano 3 h), then regional bus Tiemme line 122 Siena-Chiusdino, stop "Bivio San Galgano". Very low frequency (generally only 1 run in the morning and 1 in the afternoon, Mon-Sat, suspended on Sunday), duration 45 minutes, fare €3.50. From the stop, 700-metre walk to the abbey.
| From | Means | Duration | Cost | Notes |
|---|---|---|---|---|
| Siena | Car via SS73 | 40 min | free | Free parking |
| Siena | Bus 122 Tiemme | 45 min + 10 min on foot | €3.50 | 2 runs/day, no Sundays |
| Florence | Car via Siena | 1 h 50 | free | Link + SS73 |
| Rome | Car via A1 | 2 h 50 | free | Chiusi exit |
| Grosseto | Car via SS223 | 1 h 10 | free | Scenic road |
| Volterra | Car via SP15 | 1 h 15 | free | Colline Metallifere road |
The abbey is also a frequent stopping point for cycle tourists who travel along the Eroica and other white roads of the Val di Merse: from Siena the recommended itinerary passes through Sovicille, Brenna, Frosini and Chiusdino (about 45 km with moderate gradients, 4-5 hours on gravel or e-bike).

San Galgano Abbey is in a strategic position for exploring the less touristy southern Tuscany: the Val di Merse, the Colline Metallifere, the northern Maremma. Here are the main sites to combine in a 2-3 day itinerary:
- ●[Siena](https://en.wikipedia.org/wiki/Siena) (33 km, 40 min): the Gothic cathedral with the façade by Giovanni Pisano, the Palazzo Pubblico with the frescoes of the Good Government by Ambrogio Lorenzetti (the same author of our Montesiepi frescoes), Piazza del Campo. One day.
- ●[Chiusdino](https://en.wikipedia.org/wiki/Chiusdino) (9 km, 15 min): the birthplace of San Galgano, with the civic museum (included in the abbey ticket), the birth house of the saint and the Pieve di San Michele of the 12th century.
- ●[Volterra](https://en.wikipedia.org/wiki/Volterra) (60 km, 1 h 15): great Etruscan and medieval centre with the Guarnacci Museum, the Roman Theatre, the Duomo. It is also the city of the Asylum of Volterra closed in 1978, with the famous graffiti by Oreste Fernando Nannetti (NOF4): for enthusiasts, see our deep dive on the Asylum of Volterra and Nannetti.
- ●[Massa Marittima](https://en.wikipedia.org/wiki/Massa_Marittima) (40 km, 50 min): pearl of the Colline Metallifere, with the Pisan-Romanesque Cathedral and the Mining Museum.
- ●[Bagni di Petriolo](https://en.wikipedia.org/wiki/Petriolo) (25 km, 35 min): free and gratuitous thermal baths in the middle of the woods, with natural pools of warm sulphurous water at 43°, open 24h/24.
- ●[Castello di Sammezzano](https://en.wikipedia.org/wiki/Castello_di_Sammezzano) (110 km, 1 h 30): the incredible Moorish-style castle of Reggello (Florence), abandoned awaiting restoration, another jewel of Tuscan urbex. See our complete dossier on Castello di Sammezzano.

For those seeking a symbolic parallel with another Italian monument of mourning, we recommend our dossier on the Cretto di Burri in Gibellina, Alberto Burri's tomb-work which shares with San Galgano the same aesthetic of the ruin dialoguing with the sky.
FAQ: frequently asked questions about San Galgano Abbey
Where is San Galgano Abbey?
San Galgano Abbey is located at coordinates 43.149504 N, 11.155202 E, in the municipality of Chiusdino, in the province of Siena, in the heart of the Val di Merse. It is 33 km south-west of Siena, reachable in 40 minutes by car via the SS73.
Can you see the real sword in the stone of San Galgano?
Yes, the real sword in the stone of San Galgano is in the Chapel of Montesiepi, a small circular church one kilometre from the abbey, under a plexiglass case at the centre of the floor. Access is free and gratuitous. The analyses of the University of Pavia (2001) confirmed that the sword is authentic 12th-century and really penetrates the travertine boulder.
How much does the San Galgano Abbey ticket cost?
The full ticket costs €5.00 and includes both the abbey and the Museo di San Galgano in Chiusdino. The reduced costs €4.00 (6-18 years, over 65, groups of 20+, university students). The family ticket (2 adults + 2 minor children) costs €15.00. Free for children up to 6, accompanying persons of disabled, tour guides and residents of Chiusdino. The Chapel of Montesiepi is free entry.
What is the best period to visit San Galgano?
The best months are April, May, September and October: mild temperature, golden light, manageable tourist flow. July and August are crowded and very hot. November and February offer more suggestive atmospheres (fog, frost) but short days. Sunset is the most photogenic hour of the year.
Why does San Galgano Abbey have no roof?
The abbey is roofless because the barrel vaults of the central nave collapsed in 1781 after decades of abandonment. Five years later, in 1786, a lightning bolt also destroyed the bell tower. In 1789 the church was deconsecrated following the Leopoldine reforms of Grand Duke Peter Leopold. The conservative restoration by Gino Chierici (1924-1926) consolidated it in its current state, deliberately "without reconstruction" to respect the history of the monument.
Did the sword in the stone of San Galgano inspire the legend of King Arthur?
It is a fascinating thesis supported by the historian Mario Moiraghi in the book "L'enigma di San Galgano" (Àncora, 2003). Moiraghi notes that Galgano's sword (1180) is chronologically earlier than the first Arthurian texts with a sword in the stone (Suite du Merlin, 1200-1210; Lancelot-Grail, 1215-1230), and that the name "Galgano" shows similarities with Galvano-Gawain, one of the principal knights of the Round Table. The thesis is not universally accepted, but remains a plausible historical possibility: the Cistercian network could have transmitted the Galganian legend to the French novelists.
Is San Galgano Abbey managed by the FAI?
No, it is not part of the FAI circuit despite a frequent error. Management is entrusted to the Fondazione San Galgano, a local public-private body established in 2007. Reference site: fondazionesangalgano.it.
What famous film was shot at San Galgano Abbey?
The most famous film is "Nostalghia" (1983) by Andrei Tarkovsky: the final scene is shot under the buttresses of the abbey, with a rear projection effect that superimposes the Tuscan landscape on the protagonist's Russian dacha. Other titles: The English Patient (Minghella, 1996), Maraviglioso Boccaccio (Taviani, 2015), La chimera (Rohrwacher, 2023).
How long does a visit to San Galgano Abbey and Montesiepi last?
The complete visit (abbey + path + Chapel of Montesiepi) takes about 1 hour and 30 minutes. With the Museo di San Galgano in Chiusdino included in the ticket, count 2.5-3 hours total.
Who was San Galgano Guidotti?
Galgano Guidotti (Chiusdino, 1148/1152 - 1181) was a medieval Tuscan knight of the minor feudal nobility. After a dissolute youth, he converted in 1180 after the appearance in a dream of the Archangel Michael. He drove his sword into the rock of Montesiepi as a symbol of renunciation of military life and lived his last year as a hermit. He died on 30 November 1181 and was canonised by Pope Lucius III just four years later: one of the fastest sanctification processes in Church history.
Conclusion: what remains of the abbey and the sword
San Galgano Abbey is today one of the most powerful images of medieval Italy: a roofless Gothic cathedral in the middle of a postcard Tuscan landscape, beside a round hill that preserves the real sword in the stone: authenticated by metallurgical analyses, dated to the 12th century, driven into a travertine boulder as eight and a half centuries ago by the hand of a converted knight.
There is the spiritual history of Galgano Guidotti, young libertine become hermit in a year and canonised in four. There is the monastic history: seventy years of works (1218-1288), two centuries of splendour, two centuries of slow twilight, a lightning bolt, a deconsecration, a century of abandonment. There is the artistic history of the frescoes of Ambrogio Lorenzetti that make Montesiepi a small museum of 14th-century Sienese painting. There is the literary history of the thesis of Mario Moiraghi on our sword as prototype of the Arthurian legend, debated but chronologically grounded. There is finally the cinematographic history: Tarkovsky who in 1983 transforms the abbey into his image of exile and universal nostalgia.
All this at one hour's drive from Siena, for 5 euros of ticket, with the sky entering where the roof would be and the grass growing where the floor would be. Understanding San Galgano means understanding the Italy of living ruins, that of architectures that are not dead but have found a second life in their very incompleteness: a sword driven into the rock in 1180 that still today poses the most ancient question: where do we come from, and what are we capable of renouncing.
