The Castillo de San Pedro de la Roca (also known by the less formal title of Castillo del Morro or as San Pedro de la Roca Castle) is a fortress on the coast of the Cuban city of Santiago de Cuba. About 6 miles (10 km) southwest of the city centre, it overlooks the bay. The fortress was declared a World Heritage Site by UNESCO in 1997, cited as the best preserved and most complete example of Spanish-American military architecture.
