Écardines Bunkers

Highlight • Historical Site

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.

Many coastal poles were planted in the beach. They give the beach a beautiful stamp.
They are there to stabilize the dunes and the coast and to protect them from erosion. The poles help to maintain the dune structure and prevent them from being washed away by the wind and the water. They play an important role in the preservation of the natural environment and the protection of the coastal areas.

Galloway Cattle Observation Hide

Highlight • Rest Area

A somewhat simpler observation post. No benches and semi-open. The emphasis here is on Galloways and smaller four-legged animals, such as rabbits.

Observation point

Highlight • Other

The R219 casemate at Oye-Plage is a double embrasure gun casemate that was built as part of the Atlantic Wall during the Second World War. This casemate is located on the edge of the marsh and has now been converted into a birdwatching hut, which is a unique combination of history and nature. The R219 casemate originally had two embrasures for guns and was designed to defend the coastline from enemy attacks. The casemate is part of a larger defence complex that also includes other bunkers and ammunition bunkers, such as the nearby R134 ammunition bunker.

Ruin M272

Highlight • Other

At the location of MKB Oye Plage there were four bunkers of the type M272. These bunkers were part of the Atlantic Wall and served as gun bunkers for the German navy during the Second World War. Unfortunately, most of these bunkers have been destroyed, and only the remains of one of the four are still visible. Two of the M272 bunkers are now located under a nearby campsite.

The nature reserve offers various possibilities. The beach, the dunes and beautiful, long boardwalks. Occasionally information boards and a number of bird huts. On the beach many coastal poles and the bunkers of Escardines.

A paradise for ornithologists, the Oye Platier nature reserve is the first French stopover for many migratory birds. It has an area of 391 hectares. Shaped by the combined action of the sea, sand and wind, it is one of the must-see attractions on the Opal Coast.
