Fort Mahon, Sea fort in Ambleteuse, France
Fort Mahon stands as a stone fortification at the estuary of the Slack River, with thick walls designed to house coastal artillery batteries.
Military architect Sebastien Le Prestre de Vauban constructed this defensive structure in 1680 under the direction of King Louis XIV to protect the port.
The fort represents French military engineering excellence through its strategic placement and architectural elements that showcase period defense technology.
Visitors can access the fort every Sunday from April to November to explore exhibition rooms and view interpretive displays about coastal defense systems.
Fort Mahon remains the sole surviving coastal fort between Cherbourg and the Belgian border, featuring original battlements restored after World War II damage.
