Diagram of Fort San Marcos de Apalache

This diagram shows a bird's-eye and cross-section view of Fort San Marcos de Apalache, located on the coastal panhandle in what is now Florida. It was constructed in 1679 when the Spanish controlled the area. In April 1800, British loyalist William Augustus Bowles and a force of combined whites and Native Americans captured the fort after a five-week siege. On June 23, however, the Spanish retook the fort. It is now preserved as San Marcos de Apalache Historic State Park in St. Marks, Florida.
