The construction of the complex happened for the work of Cistercians between 1224 and 1288, the building inspires to the Cistercians churches built in the same period in France, and is the more important example gothic-Cistercian style present in Tuscany.

The abbey originated from a chapel built in 1180 from Galgano Guidotti (San Galgano), nobleman knight native of Chiusdino, that here passed in hermitage the last years of his life.

After the dead of the saint the Cistercians built in his honor a monastery, in the 13th century the monastery of San Galgano became the more important and powerful of the zone, possessing an immense territory around the abbey.

The Abbey decline began in the 14th century, when it was plundered for two times from the mercenary Giovanni Acuto (John Hawkwood, English soldier, to which Florence, as reward for his services, granted to him, as residence, the Castle of Montecchio Vesponi) and this decline was accentuated in the 15th and 16th century.

In 1577 a restoration of the structure was attempted, but the degradation was not stopped, in 1786 the bell tower collapsed (it was high 36 meters) and then collapsed also the vaulted roof.


The unfinished facade has 4 columns, over the columns are visible the projections that had to support the porch, that never was built. The structure externally measure 72 meters of length and 21 meters of width. While the portal of access is decorated with an architrave with a decoration of acanthus leaves.
