The Cathedral’s Lapidary Museum conserves and preserves around 150 works among which are sculptures and other architectural fragments. Nearly all of these come from the Cathedral and date between the 6th and 15th Century. The hall is dominated by a series of eight large sculptures bearing unusual images of monstrous and fantastic creatures, which were originally outside the Cathedral possibly on top of the diaphragm arches of the central nave. These works have been moved several times to create more room and it was the curator Roberto Salvini in 1956 suggested the current place.
