This farmland site at Manihen on the southern outskirts of the port town of Boulogne-sur-Mer was home to a series of artillery gun divisions, each bringing their own guns to the location.
The batterie started life in 1941 with four Czech-made, horse-drawn, 10cm FH14/19 field guns stood in field positions and was followed a year later by a new group the 5/AR321 with their four 10.5cm FH16 guns.
By 1943, four concrete platforms had been constructed and four 15.5cm FH414 – captured French guns – had been installed at the site by another new group positioned here, 4/Heeres Artillerie Abteilung 1144 (Army Artillery Division number 1144).
This division was replaced in 1944 by 6/AR 147 who brought four Czech-made, horse-drawn, 10cm FH14/19 field guns to the site again – the same type as originally positioned here - although at this point, they were able to use the platforms previously constructed.
In support of the four gun positions, the German occupiers built a series of bunkers, ammunition niches, and personnel shelters, the largest being an R502 double group shelter and an R134 ammunition bunker.
Three Wellblech shelters were also constructed, one of which is believed to have been used as a field dressing station or first aid post.
Little can be seen at the site today, except the tops of the concrete niches which surrounded three of the four gun platforms, the upper parts of the R502 shelter, and some heavily overgrown ruins of the Wellblech buildings.
