Hillman Site, German artillery battery in Colleville-Montgomery, France

Hillman Site is a 24-hectare German bunker complex at Colleville-Montgomery, with 18 underground concrete bunkers including two H608 command posts and an H605 gun bunker. A rounded concrete structure with a dark entrance and a camouflage net over its roof stands amid grass and bare earth, its lower front covered by dense foliage and vines.

This command post was built in 1942 as part of Atlantic Wall coastal defenses protecting German-occupied France. British forces captured it during the D-Day landings in 1944.

The site is run by volunteers of the association Les Amis du Suffolk Regiment, who have restored it since 1990. A memorial inside one bunker, donated by landowner Madame Lénaud in 1989, honours the Suffolk Regiment. The British codename Hillman followed a practice of naming nearby bunkers after British car makes such as Morris, Daimler and Humber.

The site is accessible year-round with informational panels explaining each bunker and its function throughout the grounds. Sturdy footwear is recommended since the terrain is uneven and many structures are partially underground.

The bunkers sit on elevated ground offering German defenders a commanding view over the coast and river mouth below. This positioning made them strategically valuable for monitoring naval and troop movements during the war.
