Cathedral of Our Lady of Tortosa

The Cathedral of Our Lady of Tortosa (Arabic: كاتدرائية طرطوس) was a Catholic cathedral in the city of Tartus, Syria. Erected during the 12th century, it has been described by historians as "the best-preserved religious structure of the Crusades." The cathedral was popular among pilgrims during the Crusades because Saint Peter was said to have founded a small church there dedicated to the Virgin Mary. After it was captured by the Mamluks, the cathedral was turned into a mosque. Today, the building serves as the National Museum of Tartus.
