Founded by a Knight (Nuno Alvares Pereira) in the late 14th century, it was considered to be one of the most beautiful Gothic churches around until the earthquake of 1755. It now serves as a museum showcasing the history and archaeology of the region, and inside are the tombs of many historic figures.
