Inside the small, historic village you can find the Church of San Martino, known as fuori le mura (outside the walls), the Prepositura di San Michele, next to the house where San Galgano was born, and the Church of the Compagnia di San Galgano, which is home to a fascinating bas-relief depicting St. Galgano thrusting his sword into a rock.
It’s in this very town that the legendary Abbey of San Galgano and the Hermitage of Montesiepi stand. The basilica, famous for not having a roof, is one of the main artistic symbols of Tuscany and was one of the first and most remarkable examples of Romanesque and Gothic-Cistercian architecture in Italy. The Hermitage of Montesiepi and the basilica surrounding it are without a doubt the most important religious monuments in the Sienese territory.
The Hermitage stands on the top of an oak-filled hill, where the young knight Galgano di Guidotto retired to live as a recluse in December 1180, the year in which he stuck the famous Sword in the Rock to recreate the symbol of the cross. You can still see this today in the little church of Montesiepi.
