Located to the south of the small harbour in the port town of Barneville-Carteret are the remains of a small bunker site created to protect the entrance to the harbour.
Just two buildings can be seen today, with others either removed/destroyed or partially buried in the sand dunes near the edge of the river mouth.
The open emplacement for a 5cm anti-tank gun is the most prominent of the remaining structures, now featuring a tourist map and viewpoint information board about the nature reserve the site stands in.
Just a few metres away you can also see a Vf58c type Tobruk for a MG.
