History
The Abbey of San Galgano is a Cistercian foundation in Italy, near Chiusdino in Tuscany, built chiefly during the thirteenth century in the Gothic style. It developed around the hermitage of Galgano Guidotti, a former knight who withdrew from military life and died in 1181. His religious reputation made the nearby site at Montesiepi the focus of a monastery that became one of the most influential Cistercian houses in Tuscany.
Galgano’s Hermitage and the First Community
Galgano Guidotti is traditionally described as having abandoned a dissolute youth and military career for a penitential life as a hermit at Montesiepi. On Christmas Day in 1180, he was said to have driven his sword into the ground to form a cross. The sword, hermitage, and place associated with his death became the centre of a developing religious foundation, and Galgano was later venerated as Saint Galgano.
Ugo Saladini, bishop of Volterra, commissioned a chapel at the place associated with Galgano’s death. It was completed around 1185. His successor, Ildebrando Pannocchieschi, promoted the establishment of a monastery there, and Cistercian monks were invited to form the first community, which was active by 1201.
The church at Montesiepi initially functioned as a daughter foundation of Casamari Abbey. San Galgano subsequently became a daughter house of Casamari within the wider lineage of Clairvaux. The Cistercians were a reform branch of Western monasticism that emphasized communal discipline, manual labour, austere architecture, and the self-sufficiency of religious houses.
Construction and Expansion
Construction of the large abbey in the plain below Montesiepi began around 1220. The work was encouraged by the early monastic community, Sienese nobles, and monks connected with Clairvaux. The designer was probably donnus Johannes, who had completed work at Casamari the previous year. By 1227, both the upper church at Montesiepi and the lower abbey church were recorded. An infirmary was complete in 1228, and the abbatial residence followed in 1229.
The abbey church was nearly complete by 1262 and was consecrated late in the thirteenth century, conventionally in 1288. Donations, bequests, ecclesiastical concessions, and the acquisition of property that had belonged to nearby Benedictine abbeys increased San Galgano’s resources. By the middle of the thirteenth century, it had become the most powerful Cistercian foundation in Tuscany. Emperors Henry VI, Otto IV, and Frederick II confirmed or enlarged its privileges, including the right to mint money. Pope Innocent III exempted the abbey from the tithe, a church tax.
The monastery became closely allied with the Republic of Siena. Its monks gained economic and cultural influence within the republic, and in 1257 the monk Ugo became camerlengo of Biccherna, the senior official responsible for Siena’s treasury. Other monks later held the same office. The community also helped plan an aqueduct from the Merse valley to Siena, participated in the construction of Siena Cathedral, and included Friar Melano, who contracted with the sculptor Nicola Pisano for the cathedral pulpit in 1266.
San Galgano’s activities extended beyond worship and education. The monks drained and reclaimed marshes, regulated the Merse to use its hydraulic power, and operated a mill, a fulling mill for processing cloth, and an ironworks. The abbey also accumulated property in regional towns, including Siena and San Gimignano. During the thirteenth and fourteenth centuries, it founded or controlled daughter houses at Monte Faeta, Settimo, Verruca, and Quarto.
War, Decline, and Abandonment
Famine in 1328, plague in 1348, and repeated raids by mercenary companies damaged the community and ended its expansion. The forces of John Hawkwood, an English military commander serving as a condottiero, sacked the abbey twice during the second half of the fourteenth century. By the end of that century, the resident community had fallen to about eight people.
In 1474, the monks moved to the Palazzo di San Galgano in Siena and ended their regular residence at the monastery. The abbey’s still considerable landed wealth then became the focus of conflict between the Republic of Siena and the papacy. In 1503, San Galgano was placed under commendatory administration. A commendatory abbot held the administrative title and revenues of an abbey without necessarily living there or taking part in its communal monastic life. In practice, this system accelerated the decline of San Galgano.
A commendatory abbot sold the lead from the church roof around the middle of the sixteenth century, causing further damage. A 1576 inspection found one resident who no longer wore the monastic habit, destroyed window glazing, collapsed sections of the nave vaults, and only partial remains of the infirmaries, which had been demolished earlier in the century. Restoration began in 1577, but it did not halt the deterioration.
A temporary revival around 1630 brought the community to about eighty monks under a resident abbot. The abbey soon returned to commendatory administration, however, and by the middle of the seventeenth century only four to six residents remained. The monastery appears to have closed around 1652. In 1662, the church was described as being in extremely poor condition, with rain entering throughout the building.
During the eighteenth century, Cardinal Giuseppe Maria Feroni brought Franciscans to serve the remaining complex. About ten Franciscans were present late in the century, but the abbey church was unusable, so worship took place in the sacristy. The surviving vaults collapsed in 1781, followed by the bell tower in 1786. The church was formally deconsecrated and abandoned in 1789. The monastery buildings were converted into a farm, and French troops finally closed the institution during the Napoleonic invasion.
Restoration and Continuing Religious Identity
The buildings were partly repaired during the first decades of the nineteenth century, and the complex was functioning as a farm by 1815. Local residents later removed masonry from the ruins for building material. Interest in San Galgano revived late in the nineteenth century, bringing architectural surveys, historical study, and a photographic campaign by the Alinari brothers. Giuseppe Partini carried out a restoration in 1881.
In 1924, Gino Chierici directed a conservative restoration influenced by John Ruskin. The work consolidated surviving fabric without speculative reconstruction or arbitrary additions. Part of the destroyed cloister was also rebuilt with original materials. In 1961, a Cistercian monk from Rome received permission to move to San Galgano and attempted to revive monastic life for Olivetan nuns. Several cells were restored, and a small workshop for icon painting and embroidery was established.
The abbey remains a roofless ruin affiliated with the Roman Catholic Church and the Cistercian tradition. Its religious identity is also preserved at nearby Montesiepi, where the hermitage, tomb, and sword tradition remain associated with Saint Galgano. His patronal feast is celebrated on 3 December.
Remains
The surviving complex occupies the lower Merse valley a few hundred metres from the Montesiepi hermitage and near the Via Maremmana. Its position reflects Cistercian planning preferences for sites close to major communication routes and rivers, with wooded or marshy land that could be reclaimed and used for hydraulic power. The principal remains are the roofless Gothic church, parts of the monastic buildings, the chapter house, a section of the scriptorium, and a reconstructed portion of the cloister.
The Abbey Church
Exterior and Orientation
The church is a precisely oriented Latin-cross building, with its apse facing east. It measures approximately 69 to 71 metres in length and 21 metres in width. Three naves, a broad transept, and sixteen divisions formed by cruciform piers organize the plan. The double-pitched facade reflects the division into three naves. Four engaged half-columns were intended to support a portico that was never built.
Three round-arched entrances open the facade, each with a pointed outer arch, and they are now closed by iron grilles. The central portal has a vegetal frieze with acanthus leaves. Two pointed-arch windows occupy the upper facade. Its terminal section was completed or reintegrated in brickwork early in the twentieth century. The lower side walls have splayed single-light windows with round arches, while the upper central nave has large paired windows. In the two bays nearest the transept, single round-arched windows are topped by circular openings. Most of the paired windows have lost their dividing columns, although one survives on the right side.
The left flank is faced with carefully laid, highly uniform masonry. Its transept front contains a three-light window and a buttress pierced by small openings and incorporating a small spiral stair. A portal here formerly led to the cemetery, which extended along this side of the church and was bounded by a surviving thirteenth-century brick chapel.
The Apse and Bell Tower
The apse is the most prominent surviving architectural feature and was the first part of the church visible to people arriving along the Via Maremmana. Two buttresses frame it, and two tiers of three pointed-arch single-light windows rise above the eastern end. A large decorated circular window and a smaller one occupy the upper area, with richly ornamented frames. Two further circular windows in the transept retain their original decoration.
A door and single-light window remain on the left side of the apse. They belong to the surviving portion of the bell tower, which collapsed in 1786. The presence of a bell tower was unusual for a Cistercian abbey. The church uses travertine for structural and articulating elements, while brick forms much of the walling and vaults. The eastern section has a more elaborate four-level wall elevation, whereas the western section has three levels. The choir and southern transept arm most closely follow Cistercian forms and use travertine with smaller openings; the northern transept and western bays have larger openings.
Interior and Transept
The interior has lost its roof and original floor. Compacted earth now covers the floor and becomes grass-covered in spring. Pointed arches with two recessed orders, half-columns that once supported the vaults, a double cornice above the arcades, and capitals decorated with floral forms survive in the nave. The eastern and western parts of the church are attributed respectively to donnus Johannes and, possibly, Friar Ugolino di Maffeo, who was documented in 1275.
The transept is divided into three aisles. Its eastern aisle contains four rectangular chapels arranged in pairs beside a larger central chapel, which ends in a simple rectangular apse. The chapels and smaller transept bays retain ribbed cross-vaults. Two wall niches served liturgical purposes, with the smaller one holding ampoules and the larger functioning as a lavabo.
Doors in the rear wall of the left transept lead to a spiral stair serving the former roof space and to the cemetery. In the right transept, one door leads to the sacristy. A high opening allowed monks to descend from the dormitory by a wooden stair for night and morning services. The bell tower stood beside the first chapel of the right transept, while the transept and first two longitudinal bays formed the area reserved for the monks.
An altar installed in 1288 at the second bay on the right required the removal of the base of a half-column. The upper part that remained received a new element decorated with vegetal figures. A portal in the right wall at the level of the last bay originally led to the cloister and now serves as the principal entrance to the church.
Monastic Buildings
Cloister and Sacristy
The cloister occupied the right side of the church and formed the centre of monastic life. It had been completely destroyed by the eighteenth century. Its surviving eastern side, aligned with the southern transept, includes reconstructed arcades with paired columns made from original materials. Corbels preserved on the church flank once supported the cloister portico.
The ground-floor sacristy is the first room reached from the left. It has two large cross-vaults and traces of its original fresco decoration. A pointed-arch doorway leads from it to the archive, which is also covered by a cross-vault.
Chapter House and Scriptorium
The chapter house, where monks assembled to deliberate about community governance and discipline, is entered through a pointed-arch portal. It is a large room divided into six bays by relatively low columns supporting six cross-vaults. Two large paired windows with twin columns opened onto the cloister, while three small round-arched single-light windows illuminated the rear wall.
An adjoining room has been identified as the parlour. At the southern end of the ground floor, the scriptorium, or monastic writing room, was divided into two aisles by five cruciform piers. They supported cross-vaults decorated with spiral foliage. The upper floor contained the monks’ dormitory, divided into cells, and a chapel. The lost buildings on the opposite side of the cloister probably included the refectory, kitchens, hearth, ancillary rooms, and latrines. Another side probably held the pantry, storerooms, and quarters for lay brothers, whose religious and practical duties were organized separately from those of choir monks. Lay infirmaries stood behind the cemetery and apse.
Montesiepi Hermitage
Rotonda Chapel and Sword Tradition
The nearby Montesiepi complex includes the Rotonda chapel, associated with Galgano’s hermitage, tomb, and supposed place of death. The sword traditionally attributed to him remains embedded in a stone there. It is heavily corroded and protected by a polymethyl methacrylate case.
Chapel of 1340
A chapel adjoining the Rotonda was built in 1340. Its frescoes by Ambrogio Lorenzetti, a Sienese painter, depict episodes from Saint Galgano’s life. Some of the paintings survive only as sketches, linking the physical remains at Montesiepi with the religious tradition from which the larger abbey developed.
