 This led to Gavorrano's primary importance for the whole area (as successor to the city of Massa Marittima, which had always been dominant in the area) after the war until the early 1970s (when it began to develop Follonica).After the war, the village of Scarlino became independent, breaking away from the territory of Gavorrano.A chapter in the history of the village of Gavorrano concerns the life of Pia de' Tolomei, a lady from Siena who met her death in the "Castel di Pietra", a castle in the east of the town.
