Rocca Aldobrandesca of Sovana

The ruins of the Rocca Aldobrandesca are located directly at the entrance to the town center. The castle was built in the 11th century and expanded and restored several times between the 12th and 14th centuries. It has been left to decay since the 17th century. The castle was built on a rock surface that was hewn in the Etruscan period. The only medieval city gate, the Porta della Rocca, was supposed to be defended through the castle, thus protecting the town center. In addition, the castle was originally surrounded by a moat. In 1558, under Cosimo de 'Medici, another city gate (Porta da Passo) was opened on the south side of the city. Source: Wikipedia
