The ruined Carmo Convent is said to be Lisbon's loveliest church, despite the fact it hasn’t had a roof since it fell in during the 1755 earthquake. It now stands as a reminder of the earthquake and a memorial. The beautiful gothic arches still stand and are well worth viewing. Much of the architecture dates back to the 1300s, while Manueline (Portuguese Gothic) windows and other details were added later, in the 16th and 18th centuries. You'll even be able to spot eerie South American mummies (a young boy and a young girl from Peru) if you like closely.
