The nearby Montesiepi hermitage with its mysterious Excalibur, the sword that San Galgano plunged into a rock, when he decided to abandon his life as a wealthy gentleman. Galgano’s gesture of peace and his short and intense life strongly moved his contemporaries. In 1185, only four years after his death, Pope Lucius III proclaimed him saint, and the holy bishop of Volterra, Ugo Saladini, wanted him to be buried next to the boulder that still holds his sword. The chapel was built around it, following a unique round shape.
