Battery Huger, Artillery battery at Fort Sumter, Charleston, US.

Battery Huger is a concrete artillery emplacement built into Fort Sumter's parade ground, with two gun positions and underground magazines. Its walls stand three stories high, and the structure now houses the fort's museum.

The installation was built between 1897 and 1899 by the United States Army as part of coastal defense during the Spanish-American War period. It was designed to protect Charleston's harbor from possible ship-based attacks.

Battery Huger is named after South Carolina-born artillery officer Frank Huger, who served in the Confederate army during the American Civil War. The battery's concrete casemates and gun positions were built for soldiers to watch over Charleston's harbor approaches.

The installation is accessible by regular boat service to Fort Sumter National Monument, which is the main way visitors reach the site. The grounds include museum facilities that help explain what you are seeing as you walk around.

Battery Huger's two 12-inch guns were mounted in disappearing carriages: fired over the parapet, they recoiled down behind the concrete into hiding to reload. Visitors can still see the deep gun pits and the ammunition passages cut into the battery's mass. The work was finished in 1899, and the concrete alone took thousands of barrels of cement shipped to the island.
