Camporbiano is a hill village crossed by ridge routes running parallel to the Elsa, which formerly connected San Gimignano to the Valdarno and Pisa. At Camporbiano there was also the junction of Via Volterrana, which reached the pass on the Elsa near Certaldo. Leonardo depicted Camporbiano on his renowned map RL 12278 of Windsor as a fortified village, with a curtain wall and towers. It is perfectly localized by the presence of the nearby castles, namely, Mommialla, Pietra, and Castelvecchio di San Gimignano, and it is marked by the toponym ca [m] p [or] biano. In this place, there was a fortified village dating from the 11th century: it was one of the castles controlled by the powerful Cadolingi family, the counts of Fucecchio, who owned numerous curtes and castles in the Valdelsa.
