Near the village of Hameau des Asselins lies the remains of a bunker which once housed a rare Mammut Radar System. With a range of up to 300km, the radar was used to detect shipping and direct German coastal artllery. The radar aerial originally stood on three large concrete pillars which still exist.
The inside of the bunker was protected by machine gun posts but all trace of the equipment apart from small amounts of wiring has disappeared.
