It was constructed as part of the Séré de Rivières defensive system designed to protect France after the 1870 Franco-Prussian War.
During World War II, the German army converted the fort into a primary defensive strongpoint known as 'Stützpunkt 08'.
The fort was used as a key observation post during the 1940 evacuation, located just behind the beach where thousands of soldiers awaited extraction.
The site was officially designated as a protected natural space due to the sensitive dune ecosystem surrounding the masonry structures.
It suffered significant damage during the heavy shelling of the Dunkirk pocket in 1940.
The fort was restored in the early 2000s to convert the former military barracks into a historical museum space.
Several bunkers on the site feature original graffiti and markings left by soldiers during the occupation.
Fort des Dunes is a 19th-century military fortification located within the dunes of Leffrinckoucke near Dunkirk. Originally built between 1878 and 1880 to defend the coastline, the fort serves as a historical site commemorating the Battle of Dunkirk and Operation Dynamo. The site retains significant World War II bunkers and exhibits detailing the German occupation and the local resistance. Its strategic positioning within a protected natural dune environment offers both historical insight and a coastal trail network. The museum highlights the fort's evolution from a coastal defense system to a German defensive position during the Atlantic Wall construction. Visitors can explore the preserved casemates, underground galleries, and outdoor installations. The site remains a rare example of a Séré de Rivières fort adapted for 20th-century warfare. It currently functions as a memorial and educational space focused on the 1940 evacuation.

Combine your visit with a walk through the surrounding protected dunes for views of the North Sea.
Do not attempt to explore abandoned, unmarked concrete bunkers outside the designated museum perimeter for safety reasons.
Closed on Mondays and throughout the month of January.
Refrain from climbing on non-reinforced masonry and follow paths to preserve the fragile dune vegetation.
