Fort Mose Historic State Park is a U.S. National Historic Landmark, located two miles north of St. Augustine, Florida, on the edge of a salt marsh on the western side of the waterway separating the mainland from the coastal barrier islands. The original site of the 18th-century fort was uncovered in a 1986 archeological dig. The 24-acre site is now protected as a Florida State Park, administered through the Anastasia State Recreation Area. Fort Mose is the "premier site on the Florida Black Heritage Trail".
In 1738, the Spanish governor of Florida, Manuel de Montiano, had Fort Mose constructed and established it as a free black settlement, the first to be legally sanctioned in what would become the territory of the United States. The fort has also been called Fort Moosa or Fort Mossa, variants of the Spanish pronunciation.
