7. Visit a classic crypt furnished with bones
For the bolder, the crypt of the Capuchin friars provides a weird and sinister sight; since 1631, bones of 5,000 dead friars decorate the walls as well as ceiling. Check out the crypt of skulls, the crypt of leg bones and the crypt of pelvises, all elaborately ornamented with bones of their corresponding names — scary to believe, nevertheless true.
