Fort Sumter and Fort Moultrie National Historical Park

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.
