Throughout its history, the story of Fort Matanzas has been closely intertwined with that of the city of St. Augustine and the Castillo de San Marcos. This Spanish outpost fort was built in 1740-1742 to guard the Matanzas Inlet and to warn St. Augustine of British or other enemies approaching from the south. Fort Matanzas now serves as a reminder of the early Spanish empire in the New World.
In addition, the park, which is located on barrier islands along the shores of the Atlantic Ocean and the Matanzas estuary, provides a natural habitat rich in wildlife with the salt marsh, scrub, and maritime hammock now protecting endangered and threatened species like the historic Fort Matanzas protected St. Augustine long ago.
