Castillo De San Marcos National Monument
America Begins Here
St. Augustine, founded in 1565 by Spanish exporers led by Pedro Menendez, has witnessed centuries of history from the earliest colonial times to the present. Even before being founded by Europeans, this active coast was home to indigenous people including the Timucuan.
Built in 1672 to defend Spanish Florida and the Atlantic trade route, Castillo de San Marcos National Monument preserves the oldest masonry fortification in the continental United States.
Explore over 300 years of Florida history as you make your way through this fortress built in the late 1600s. From its commanding position on the waters of Matanzas Bay, a garrison of Spanish troops safeguarded St. Augustine during the turbulent colonial era. Later English and then American troops also saw service here. Exhibits highlighting various chapters of the fort’s long history are found in the historic storerooms that surround the central courtyard. Beautiful views await on the Castillo gundeck.
