The Palazzo Comunale anchors the central piazza and is the single most photographed building in town. The composition — a long, low slab in white travertine with a tall, severe brick clock tower attached at one end — is a textbook example of Italian rationalism, and unusually well preserved. The clock face is plain; the bell at the top still rings the hours.
Inside, the council chamber retains its original 1930s fittings, including period light fixtures and an apse fresco. The exterior arcade along the piazza is a favourite local meeting point, especially around aperitivo time, and a sequence of bas-reliefs on the tower commemorates the draining of the marshes and the founding of the town.
