Architectural works of Foiano include the 14th century Palazzo Pretorio along one side of Piazza Cavour, and the Palazzo delle Logge on the other, built between the 16th and 17th centuries. The Palazzo delle Logge was the residence of Ferdinando II de Medici and the Municipal Historic Archive and the Library are now housed inside, with some of the halls used for exhibitions. The Civic Tower has been recently restored, preserving its original proportions and façade.
