Access to the crypt and the garden with a beautiful fountain is from the monumental portico on the south side of Piazza San Francesco. The crypt, actually a small noble chapel never intended for the deceased of the Rasponi family – is the oldest nucleus of the architectural complex of Palazzo Rasponi, probably dating back to the end of the 18th century. The crypt consists of three rooms: the access one is inserted into the base of a neo-Gothic turret; in a room there is a beautiful stone ball with the inscription SIC VITA PENDET AB ALTO; the presbytery is intended to house a small altar for religious functions.
