Volterra's city hall is probably the oldest in Tuscany, at nearly 800 years, and inspired the design for the Palazzo Vecchio in Florence. The lavishly painted city council chambers are open to the public when not being used for official meetings.
The Palazzo dei Priori is a Gothic-style monumental civic building in the center of the town of Volterra, located on the Piazza dei Priori, also known as Piazza Maggiore. The imposing 13th-century stone building once the office of appointed town magistrates, still has offices of the local commune, including the communal council, for Volterra, province of Pisa, region of Tuscany, Italy.
