One of the largest and most important Confederate forts of the Civil War. Walk the massive earthwork remains and visit the free museum explaining the history. The fort protected Wilmington - the last major Confederate port - until falling in January 1865 after one of the war's largest naval bombardments. Impressive grass-covered mounds with interpretive signs. Visitor center has artifacts and fiber optic battle map. Free admission. Near the aquarium and Southport ferry. Allow about an hour.
