National Park Service, South Carolina.
Two forts stand at the entrance of Charleston Harbor. Patriots inside a palmetto log fort, later named Fort Moultrie, defeated the Royal Navy in 1776. As Charleston blazed a path towards secession to preserve slavery, construction on a new fort, Fort Sumter, proceeded. The Confederacy fired on the US garrison of Fort Sumter on April 12, 1861 opening the Civil War, which redefined American freedom.
Entrance passes purchased through recreation.gov are for access to the Fort Moultrie site only. Fort Moultrie is located on Sullivan's Island and can be driven to.
