"In 1755, Lisbon was all but devoured by an earthquake so strong that it still ranks as one of the most destructive in recorded history. One of the few structures to survive somewhat intact was the Carmo Convent—an impressive feat, considering it was built in the 14th century. Today, you can still tour its beautiful skeleton, complete with soaring archways that cut a majestic path across the sky. Also worth visiting is the open courtyard, which houses spillover ruins from the attached archaeological museum."
