The Pio XII Museum offers visitors a walk through history, from the Palaeolithic period to the Iron Age, from Romanization to the Christian era. Each era is documented with abundant traces. Among the exhibits, the highlights are: a gladiator (in bronze), a grand dolium and a Roman mosaic, the last resulting from excavations in the Cloister of the Conciliar Seminary of S. Pedro and S. Paulo that discovered a Roman Domus. Sacred art is also well represented, through the collections of sculpture, painting, ceramics and jewelery, in a very rich collection that dates back to the 14th century.
