Fort de l'Eve, Coastal defense fort in Saint-Nazaire, France.

Fort de l'Ève is a coastal artillery battery on the Ève promontory at the Loire estuary entrance in Saint-Nazaire. Its concrete structures include a wide, low pyramidal roof with a short square chimney block at the apex, a projecting horizontal band above the lower wall, and a recessed rectangular opening in the roof face. The walls and roof are covered in sprayed graffiti, with large painted lettering including "SLAP" beside a green triangle and a yellow shape; overgrowth crowds the left and right edges.

Construction took place between 1891 and 1895 as part of France's coastal defense system. It played a key role during both World Wars, especially under German occupation from 1940 to 1945.

The fort's name comes from the Ève promontory at the Loire estuary mouth. German sailors of 3./MAA 280 renamed the battery "MKB Bencke" and lived on site with 151 men. The site is now used for recreation, with a camping area and beach beside the old works.

The fort stands on the Ève promontory at the Loire estuary mouth, on the Saint-Nazaire commune in Loire-Atlantique. The site is reached by the Route du Fort de l'Ève; the concrete battery, its rock store and firing platforms sit among overgrowth, so expect uneven ground underfoot.

The original military installations were partly converted into a camping area and equipped beach. This reuse has allowed the site to function as both heritage location and recreation space today.
