Chapel of Bones

from Chapel of Bones in Evora, Portugal

This 16th-century chapel is lined with the skulls and skeletons of about 5,000 people from local cemetaries, plus two leathery corpses hanging from the ceiling for unknown reasons. The macabre display was created by a couple of monks who wished to contemplate the transitory nature of life — and communicate that message to others. A painted note over the entrance reads, "Our bones that are here await yours."
