Fort Moultrie National Historical Park

On April 12, 1861, the first shots of the Civil War were fired at Fort Santer. After 34 hours of fighting, the Allied Northern Army surrendered, and Fort Santer became a symbol of resistance by the Southern Army. From August 1863 to February 1865, despite the constant bombing, the Confederate forces kept Fort Santer. When they finally evacuated, there was only a pile of rubble left. The current National Park System (NationalParkService) overlooks it. Located next to the South Carolina Aquarium (SouthCarolinaAquartum), the Fort Santer Freedom Square Visitor Center (FortsumterLibertysquareVisitorCenter has many exhibits about the Civil War. From here, you can take a ferry to the small island where Fort Santer is located.
