2. Most Chilling Church – Chapel of Bones (Evora, Portugal)

Creep inside the Church of São Francisco, and a chill will certainly run up and down your spine. As one of the world’s creepiest attractions, the Capela dos Ossos is walled and columned with bones from over 5,000 exhumed skeletons. Arches created from ribs and tibias, skulls and vertebrae forming artistic designs; this chapel is no place for those who fear the great beyond. Each bone is meticulously placed by the artists, 16th century Franciscan monks, and the entrance warns those who dare to cross the threshold that your bones will be next: “We bones, lying here, for yours we wait.”
