The Bone Chapel, or Capela dos Ossos, is a small chapel located in the city of Évora, Portugal. It is famous for its interior walls decorated with human bones and skulls, which were taken from the nearby cemetery. The chapel was built in the 16th century by Franciscan monks to remind visitors of the inevitability of death. The chapel features a striking inscription that translates to "We bones that are here await yours." This message serves as a memento mori, encouraging reflection on mortality. The Bone Chapel is part of the larger Church of St. Francis, attracting many tourists and those interested in history and art.
