Bayou Bienvenue

Bayou Bienvenue is a 12.1-mile-long (19.5 km)bayou in southeastern Louisiana. It runs along the political border between Orleans Parish and St. Bernard Parish to the east of New Orleans.

The bayou crosses the Gulf Intracoastal Waterway and Mississippi River Gulf Outlet, before ending in Lake Borgne, a shallow estuarine lake branching from the Mississippi Sound.

A short distance from the Lake end of Bayou Bienvenue, the remains of Battery Bienvenue still guard the eastern approach to the city. This fortification was built shortly after 1815's Battle of New Orleans to prevent any future invasion of the city by way of the Lake and Bayou.
