"This 15th-century "Cathedral of Bones" is a fascinating look at Evora's dark past—it's creepy, but it's a must. Situated next to The Church of St. Francis, the building is unassuming on the outside, yet the interior is covered in (gulp) human skulls and bones, all built in the 16th century by a Franciscan monk. The church itself might be small in size, but the impact it has on those brave enough to enter is profound—and that was the intention." - Jenna Scatena
