A Capuchin church sits atop a macabre sight: a crypt decorated in the 18th century with the bones of 3700 Capuchin monks as a memento mori (reminder of death). Six chapels line a 30m-long passageway, each named after the bone lovingly used to decorate it. There's even an arch crafted from skulls, vertebrae used as fleurs-de-lis, and light fixtures made of femurs. An audio guide is included with the ticket.
The small museum is home to a work attributed to Caravaggio: St Francis in Meditation (c 1603).
