You can reach the ancient Hermitage and Abbey of San Galgano by taking the road that goes from Siena towards Massa Marittima and Follonica. Today all that remains of the Abbey are its roofless walls and the transepts but this makes it even more suggestive. The canon's house and other buildings are still intact. The hermitage on the hill above contains the famous sword in the rock where the warrior Galgano used to kneel in prayer.
