The Abbey of San Galgano was built in the 13th century around the site of the former hermitage of Galgano Guidotti (San Galgano), experienced a period of great wealth and prosperity, and in the 15th century began to decline.
But the main secret of this place is the sword stuck in the stone.
Legends say that it was the sword of a knight named Galgano Guioti, who was led to the Montecity hill by visions. A miracle happened here: the sword easily entered the stone - and remained there forever. Knight Galgano renounced his worldly pursuits, became a hermit, and in the 12th century was canonized.
