Located in Sullivan's Island, Fort Moultrie's history covers 171 years of seacoast defense, including the first decisive victory in the American Revolution and the firing onto Fort Sumter during the first battle of the Civil War. The third Fort Moultrie, built in 1809, stands today. By touring the fort, visitors can see how coastal defenses have evolved.

America's most tragic conflict ignited at Fort Sumter on April 12, 1861, when a chain reaction of social, economic and political events exploded into civil war. At the heart of these events was the issue of states rights versus federal authority flowing over the underlying issue of slavery. Fueled by decades of disagreement and confrontation, South Carolina seceded in protest of Lincoln's election and the social and economic changes sure to follow. With Fort Sumter as an unyielding bastion of Federal authority, the war became inevitable. A powerful symbol to both the South and the North, Fort Sumter remains a memorial to all that fought to hold it. Fort Sumter National Monument includes historic Fort Sumter located in Charleston Harbor, the Liberty Square Visitor Education Center and departure facilities in Charleston at 340 Concord Street, and Fort Moultrie, located on Sullivan's Island.
