The Castillo de San Marcos National Monument contains the original Castillo de San Marcos, a fortification built by the Spanish to defend their position in America. It is the only remaining 17th-century fort in North America. The star-shaped "bastion system" of the architecture was an adaptation to cannon warfare. The monument presents the story of several groups involved in the fort's history, including the Timucuan, the Seminole, the Apache, Spaniards, African Americans, Englishmen, Frenchmen, Minorcans, and U.S. citizens. Interpreters in period dress discuss life in the fort.

The monument offers a 25-minute introductory film, exhibits, self-guided fortification tours, interpretive talks, re-enactors, weaponry demonstrations, Junior Ranger programs, and a green suitable for picnics. The upper gun deck is not wheelchair accessible. Tour brochures are available in English, Spanish, German, Japanese, French, Italian, Dutch, and Russian. The website offers historical photographs, vocabulary, a map study, and other educational materials.
