Placed at irregular intervals around three sides of the perimeter of White Point Garden are several military relics. Along East Battery are the 11-inch Dahlgren gun from the USS "Keokuk" that fired shells at Fort Sumter in 1863 and two Confederate columbiads (large cannons) that were used in the defense of Fort Sumter. On Murray Blvd. there are several more artillery pieces: a rare 7-inch Brooke rifle (a large cannon) that was found at Fort Johnson and four 13-inch Union mortars (weighing 17,000 pounds each). On the King St. side are a 1918 World War I howitzer; a French cannon of Revolutionary War vintage that was found in Camden, South Carolina; and a rapid-fire gun from a Spanish ship captured during the Spanish–American War.
