Lions Gate, also known as St. Stephen's Gate (Chatham University Archives) The "lions" carved on both sides of the gate are actually panthers, the symbol of the Mamluk Sultan Baybars (1223-1277). The panthers were believed to have been part of a Mamluki structure and placed at the gate by Suleiman to commemorate the Ottoman victory over the Mamluks in 1517.
