Ponzanello is an ancient fortified village located between Aulla and Fosdinovo, perched on a strategic hill that overlooks the surrounding valley. The earliest records of Ponzanello date back to 1185, already recognizing it as a significant settlement. It later became documented as the seat of the Bishops-Counts, housing their archive, library, and treasury.
It is believed that Ponzanello was organized as a municipality as early as 1200, making it one of the first free communes in Lunigiana. Among the village’s oldest buildings are the Church of San Martino, also known as the Old Church (12th century), and the Chapel of San Filippo Neri, or New Church (13th century).
Though the Castle of Ponzanello is not open to the public, its imposing structure still dominates the landscape. Historically, the castle was protected by four gates and even a triple set of defensive walls—evidence of its strategic and military importance.
