Bone Chapel, Hallstatt, Austria. Hallstatt's graveyard is so small, that after 12 years they would dig up the bones, decorate them, and put them in the chapel.

Some of the bones date back to the 1600s; the most recent are from the 1960s (when the Catholic church began to allow cremation and the space issues were not so problematic). Many of the skulls are painted with wreaths of ivy, garlands of roses, black crosses, and the owners' names, professions, and death dates.
