For this very special day I decided to introduce you to a place where my passion for history began, it is here that I acquired my very first history book that deals with the remains of the Atlantic Wall.
To direct the firing of the Batz-sur-Mer guns and control maritime traffic between Belle-Ile-en-Mer and Noirmoutier, the construction of a heavy fire management post (PDT) type S 414 was decided during the second half of 1942.
It will be installed on the rocky promontory of the Dilane, 16 metres above sea level. The fifth level housing the rangefinder will be 28 metres high. Construction of the shell began on 22 October 1942 and was completed on 8 February 1943.
The first workers to install the metal skeleton of the bunker with 125 tons of iron were mainly North African workers stationed at the African II camp in Pouliguen. They are supported by about a hundred workers working for the German construction company Polansky and Zöllner, under contract with the Todt Organisation.
About fifty carpenters worked for several weeks to form the entire metal skeleton of the building with wood. Then the liquid concrete is poured for 27 hours! This 25-metre long structure with a maximum height of 17 metres required 1,800 m3 of concrete, which represents 300 trucks of 6 m3!
Its interior space is 285 m2, the walls overlooking the outside and the ceilings are 2 metres thick everywhere.
Almost alone on the moor and set on a rocky promontory, the blockhouse is very visible. In February 1943, he was camouflaged in a large villa.
Because of the permanent presence of troops in the building, everything is planned for the comfort of the men: the rooms are heated by radiators, part of the floor is tiled and some walls are covered with panelling.
Two rooms are equipped with toilets and washbasins with running water, which is rare at that time.
The watertight doors and filtered air circulating in the blockhouse allow soldiers to live independently, even in the event of an attack by poison gas.
With a supply of water and food as well as an infirmary, the blockhouse is autonomous to hold several days in case of combat.
