This Capucin complex safeguards Rome's strangest sight: a crypt where everything from the picture frames to the light fittings are made of the bones of 3700 Capuchin monks as a macabre memento mori (reminder of death). Created between 1732 and 1775, six chapels line a 30m-long passageway, each named after the signature bone used to decorate it (The Crypt of the Pelvises, for example). There's even an arch crafted from skulls, vertebrae used as fleurs-de-lis, and light fixtures made of femurs.
The accompanying multimedia museum tells the story of the Capuchin order of monks and is home to a work attributed to Caravaggio: St Francis in Meditation (c 1603). Don't miss the adjoining Chiesa dei Cappuccini (1626), accessible via the outside staircase. Hiring an audio tour (in Italian, English or Spanish) costs €5.
