On the beach to the North of Les Ecardines there are some bunkers which belong to the Infantry Stützpunkt Martha. This strongpoint with 2 bunkers laying on the beach was part of the coastal defence and observation. One of the bunkers on the beach is a Regelbau R120 observation bunker with a 21P7 metal cupola on top. It has three entrances and a armoured close defence opening for a MG. A flanking wall lies next to it in the sand. Next to the observation bunker is a Regelbau R630 type bunker. It housed a gun behind a big armoured plate. The armament of Strongpoint Martha consisted of MG’s in the R630 (MG stand for Machine Gewehr – machine guns), a 5cm M19 mortar, a 5cm gun, a 3,7cm Anti Tank gun, a MG-cupola, 2 Mortars and 5 MG’s. This heavily defended strongpoint housed the observation bunker of HKB Murane, as well as the headquarters of the 8th kompagnie. These bunkers, are part of a Luftwaffe Field Division instead of the Kriegsmarine. InfStp. Martha has eight bunkers in total. The other bunkers of this strongpoint can be found further up the dunes.

A remnant of the Atlantic Wall and thus of the Second World War. Not necessarily beautiful but important as a memorial.
