See the human skulls and bones at San Bernardino alle Ossa chapel in Milan, Italy. Explore the unusual and extraordinary chapel built in 1695 because the nearby cemetery ran out of space. Somewhat hidden off the main church, skulls, leg and arm bones are wall mounted in various cruciform patterns. Some debate exists as to the origin of the bones from the decapitated heads of criminals, to illegitimate children or martyrs from the Arian massacres. Even more debatable is visitors' take on the attraction from freakish and bizarre to delightfully disturbing.
