Beneath the pretty-in-pink Chiesa di Santa Restituta church, rebuilt after the 1883 earthquake, be sure to visit the Area Archeologica. Excavations undertaken between 1951 and 1974 have uncovered parts of an ancient Greek kiln, a Roman temple and street, 4th-century burial amphorae and an early Christian basilica. Rows of cabinets display other ancient objects, from Roman bracelets and votive gifts to a 3300-year-old stove from Procida.
The ground-floor collection features exquisite 17th-century pastori (nativity-scene figurines), colourful 18th-century ceramics, high-camp clerical garb and the 18th-century wooden statue of Santa Restituta still used in the annual procession in the Bay of San Montano. You can borrow an informative, handwritten guide to the excavations from the ticket desk.
