This brick fort was built in 1822 to protect New Orleans. It was originally named Fort Chef Menteur until it was renamed Fort Wood in 1827. It was renamed again in 1851 after General Alexander Macomb. In the American Civil War, it was controlled by the Confederate army in January 1861 until it was regained by the Union in 1862. After a fire in 1867, it was abandoned and decommissioned in 1871. It has deteriorated to the point that it is off-limits to the general public.
