Battery Bienvenue

 (1815-1872) - Battery Bienvenue was a Third System coastal gun battery in Bayou Bienvenue, St. Bernard Parish, Louisiana. Deactivated in 1872.

Third System (1816-1867)
This battery was located at a strategic "Y" where Bayou Bienvenue and Bayou Villere join as Bayou Bienvenue winds from Lake Borgne toward New Orleans. This was the route used by the British in the War of 1812 to approach the city.

This battery was first constructed in 1815 and improved over the years. The initial armament was planned for one 24 pounder and two 18 pounder cannons. In 1826 the plan expanded to twenty four 24/32 pounders and two 13 inch mortars with a garrison on one artillery company. Eventually four buildings occupied the parade, a barracks, officer quarters, a guardhouse and a magazine. The battery was about 600 feet wide with the guns pointed right down Bayou Bienvenue. The battery was surrounded by a moat that connected to Bayou Bienvenue.

The Battery was abandoned after the U.S. Civil War in 1872.
