St. Marks Lighthouse
Built in 1842, the St. Marks Lighthouse played a pivotal role during the Civil War. Despite its light being quenched during the war, it remains a working lighthouse marking the location of the St. Marks River.

Stretching across 70,000 acres in Florida’s Big Bend, St. Marks National Wildlife Refuge protects one of Florida’s longest wild shorelines, more than 43 miles in three counties.
