Fort Pike

A fort had been constructed in 1793 at Petit Coquilles, and was the intended destination of Jones's gunboat squadron prior to the Battle of Lake Borgne. General Jackson's engineer, Major Latour, lamented upon the state of the fort in 1814. Postwar, it was decided to improve the coastal defences with the creation of Fort Pike commencing in 1819 to replace the earlier fort. It was the first of three forts to be constructed in Louisiana under the postwar "Third System", along with Fort Jackson, Louisiana, and Fort Livingston, Louisiana. During the Seminole Wars in Florida through the 1820s, the US temporarily held Seminole Indians here who had been taken prisoner. They were eventually transported to the Seminole Reservation in Indian Territory (now Oklahoma.)

The Louisiana Continental Guard took control of the fort in 1861, just weeks before Louisiana joined the Confederacy and the American Civil War began.

When Union forces captured New Orleans in 1862, the Confederate forces evacuated Fort Pike. The Union reestablished control of the installation, using it as a base for raids. The fort also became a site for training of United States Colored Troops, established in 1864. These soldiers in the South included mostly former slaves.

The fort was abandoned by the United States Army in 1890. No cannon was ever fired in battle at Fort Pike. It was listed on the National Register of Historic Places in 1972. It was maintained as part of a state park, known as the Fort Pike State Historic Site.

Before Hurricane Katrina, the fort's brick-and-mortar structure was decaying. The 2005 storm surge exacerbated the problems. It temporarily completely submerged the entire fort, and destroyed adjacent state park buildings. The site officially reopened on May 2, 2008. However, due to damage caused by Hurricane Gustav in early September 2008, the park was closed indefinitely. As of June 2009, the fort was open. It is undergoing extensive repairs and restoration work. After Hurricane Isaac in 2012, the fort was closed indefinitely pending repairs and debris cleanup.

The fort was re-opened to visitors following Hurricane Isaac, but closed again in February 2015 due to state budget cuts.
