On one of our trips we drove though the remnants of Battery Oye Plage.
At first we encountered an ammunition bunker, Regelbau R134. It has oval armoured doors, like the construction style of the West Wall, or Siegfriedline.
It was engulfed in thorn bushes but we managed to get some photos.
The Leitstand or Fire Control Tower is camouflaged as a church tower.
The bunker is tilting heavily due to a demolition attempt from the Allied Foreces right after the Second World War.
The original two part armoured door is still visible in the Fire Control bunker.
The battery was under the command of MKB 204. MKB stands for Marineküstenbatterie, marine coastal battery, a section of the Kriegsmarine who controlled a part of the Atlantic Wall.
Battery Oye Plage is much bigger than these two objects.
With several M270 regelbau types which housed four 15cm TbsK C/36 guns, personnel bunkers and more. (See Battery Waldam for the size of the M270 bunkers)
You can find the ammunition storage and the Fire control bunker on Route des Dunes from Oye Plage to Grand Fort Phillipe in Northern France.
On the same route, drive to the beach in the corner from Route des Dunes and Rue de la Mer to see this Anti Tank Wall with MG post.
