San Marcos de Apalache Historic State Park

San Marcos de Apalache Historic State Park is a Florida State Park in Wakulla County, Florida organized around the historic site of a Spanish colonial fort, which was used by succeeding nations that controlled the area. The Spanish first built wooden buildings and a stockade in the late 17th and early 18th centuries here, which were destroyed by a hurricane.

The stone fort was built beginning in 1753. It came under successive control by Great Britain, Spain, the United States and, lastly, the Confederacy during the American Civil War. A U.S. Marine Hospital was built from the materials of the fort. The US took control of the site again in 1865, and the fort site was abandoned.
