The Capela dos Ossos is one of the best known monuments in Évora, Portugal. It is a small interior chapel located next to the entrance of the Church of St. Francis. The Chapel gets its name because the interior walls are covered and decorated with human skulls and bones.
The Capela dos Ossos was built by Franciscan monks. An estimated 5,000 corpses were exhumed and to decorate the walls of the chapel. The bones came from ordinary people who were buried in Évora's medieval cemeteries. In any event, the Franciscans arranged the bones in a variety of patterns.
