Fort Fisher was built by Confederate forces during the American Civil War to protect Wilmington, North Carolina. It fell on January 15, 1865 after hours of brutal fighting. Since then, visitors to the fort’s ruins have reported numerous strange encounters, including sightings of a mysterious sentinel, as well as its commander, Col. William Lamb. Others report hearing disembodied footsteps, phantom screams, and gunshots. In 1961, the site was declared a National Historic Landmark and added to the National Register of Historic Places five years later.
