Museum and Crypt of the Capuchins
One of the most macabre, and therefore hugely popular, sights in all Christendom. This museum dedicated to the Capuchin Order ends with an eerie series of six chapels in the crypt, adorned with thousands of skulls and bones woven into mosaic “works of art”.
The experience is undeniably spooky and you can take pictures. The entrance is halfway up the first staircase on the right of the church of the Convento dei Frati Cappuccini, completed in 1630 and rebuilt in the early 1930s.
