A castle of the Gherardesca counts (half given away in 1004; Count Ildebrando gave half his share to the archbishopric of Pisa in 1139) that came under Pisa's rule in 1158 when the archbishop acquired the holdings of the Serena abbey.
Above it on Monte Calvi stands Rocca San Silvestro, the mining castle founded by the Gherardesca and held in the twelfth century by the Della Rocca family; its copper and silver-bearing lead are in decline by the end of the twelfth century in the face of Sardinian competition.
