Fort Mahon, Ambleteuse
Fort Mahon (Fort Vauban)
A 17th-century Vauban-style coastal fort standing on the sand, with the Slack estuary and the small village of Ambleteuse behind it.
Fort Mahon was designed by Vauban and completed in the 1680s. It is a small round coastal fort standing on the intertidal sand, surrounded by the sea at high tide, which makes it very photogenic. The fort is open to visitors in summer for a small admission fee, and at other times can be viewed from outside. The Slack estuary and dunes beside it are good for birdwatching and walking, and the village has a Second World War museum. It is about 5 km from Wimereux.
