Strongpoint Bruno may be a small bunker site to the east of Dunkirk near to the border with Belgium, but it boasts one of the largest constructions in the area.
This is a R636 command bunker for a coastal batterie and would have been vital for range finding and targeting for the many batteries in the vicinity.
A R506 casemate for a 4.7cm Skoda fortress gun can also be found here along with a several Tobruks, a machine gun post, and a Ringstand for a 5cm KwK anti-tank gun. This structure has the unusual addition of a brick-built wall on top of the concrete base to give the gun crew added protection.
