Évora, Portugal, offers up the Chapel of Bones, and is in the Church of St Francis. It is a small interior chapel near the entrance, the chapel walls are covered and decorated with human skulls and bones.
It was built by a Franciscan monk in the 16th Century, the counter-reformation spirit was what he had hoped to capture. He wanted to prod his brothers into further contemplation.
There is a warning at the entrance that reads “Nós ossos que aqui estamos pelos vossos esperamos” which means ‘We the bones that are here, await yours.’
About 5000 skeletons were used and came from cemeteries situated inside several churches around the area. A visit to the church may not be for the feint of heart, but sounds intriguing none the less.
