Symbol representing the towns of Sovana, Sorano and Pitigliano is tuff, an element that has always characterized the area, the whole territory is of volcanic origin and is indented by enormous buttresses carved tufa rock from many rooms, once inhabited and still used today as storage or shelter for farm implements.

Tuff is linked to the history of this part of Maremma, over time this rock has allowed ancient peoples prehistoric, Etruscan and medieval to exploit and shape the area with cemeteries, roads, columbaria and more.

Even the exiting villages with the houses leaning against each other and built in tuff, give the impression of being one with the rocky cliffs below.
