The Castillo de San Marcos National Monument is an impressive sight. Built by the Spanish in St. Augustine to defend Florida and the Atlantic trade route, it is the oldest masonry fortification in the continental United States. The Monument preserves and interprets more than 450 years of cultural intersections. It is a place where you can learn about the history of the Spanish colonization of America, the conflicts between the European powers, and the struggle for control of Florida. You can also see how the Native Americans, Africans and Cubans who made Florida their home have shaped its culture. The Castillo de San Marcos is a fascinating place with a rich history, and it is well worth a visit.
