Located on the ground floor of the Town Hall, former Palazzo Berarducci  dating back to the seventeenth century, the museum was transferred to Palazzo Coppetti. It houses a small but significant collection which encompasses paintings from the church Santa Maria del Capoluogo  and archaeological remains found at the cemetery’s chapel.

Here you can admire La Madonna del Rosario by Benedetto Nucci (1515 - 1587) and two paintings by Ernst van Schayck (1567-after 1631): Il Crocifisso tra San Girolamo, Santa Maria Maddalena, San Francesco and La Vergine col Bambino, San Michele Arcangelo, San Carlo e San Bernardino da Siena.

An elegant loggia from the end of the sixteenth century grant you a wonderful view.

Remains from the Roman period found in a Roman villa in Mattonato district are here on display together with materials collected in recent times such as fragments of mosaic floor, architectural decorations, fragments of amphorae and various pottery from the Roman era, roughly dating back to the late Republican era and to the first century A.D.

The  big collection of the museum has been recently enriched with other important documents from "Anita Garibaldi Jallet" (photographs and written witnesses concerning Garibaldi-Canzio families) and "Romiti-Mosullani" photographs and documents related to Joseph and Anita Garibaldi together with Garibalda Canzio’s memories).
