Oct. 14 NCIS: New Orleans episode shows Fort Macomb tunnels, bastion

Fort Macomb, a 19th century fort designed to protect New Orleans, was used in the Oct. 14, 2014, episode of NCIS: New Orleans.
It’s true: The Oct. 14 episode of NCIS: New Orleans included a scene inside Fort Macomb. See the original post here.
Remember when cast members Scott Bakula (aka Special Agent Dwayne “King” Pride) and Zoe McClellan (aka Special Agent Meredith “Merri” Brody) found the secret escape route in the fraternity house and then walked through those dark tunnels? Those tunnels were actually within the walls of Fort Macomb. And when they stepped through that hole in the wall, Bakula and McClellan were actually in the bastion, which sits in the parade grounds of the old military installation.
