In this article a construction of the Atlantic Wall discovered on 02/01/2006 near the Pointe Saint Mathieu (Finistère, France) is identified and its purpose is clarified. It witnessed the presence, during the World War II, at Pointe Saint-Mathieu, of a Kieswerk or pebble factory in which the pebbles and/or crushed pebbles of the Ero Vili were stored and distributed. The Kieswerk was very likely to have participated in the construction of the Atlantic Wall fortifications of the Pointe Saint-Mathieu.
Looking to the impressive defensive fortifications of the Atlantic Wall (Chazette et al., 1995; Dupont & Peyle, 1994; Duquesne, 1976) , sometime the attention of the people is distracted from the enormous efforts and the logistic structure behind that, which allowed the construction of them. Many of the components of this structure have disappeared, but sometime here and there some of them can still be recognized and identified.
The Kieswerk of Pointe Saint-Mathieu (48˚20'10.5''N, 04˚46'2.9''W)
On 02/01/2006, during an excursion on Pointe-Saint Mathieu (Finistère, France) (cf.
At the pebble factory of Camp Todt (Tomezzoli, 2015) , the Ero Vili pebbles collected on the Tronoën beach were loaded on convoys of wagonettes. Locomotives Decauville brought each convoy on the top of a massive
wall about 150 meters long, 2 meters wide and 10 meters high. From that height, workers manually toppled each wagonette so as to drop the pebbles into screening silos. From those silos, the small pebbles directly usable in construction fell into the wagons of a railway convoy parked at the base of the wall. The too large pebbles not usable in the state were collected in other convoys of wagonettes driven by loco-tractors and stored outside a crushers building (about 20 × 13 meters). Conveyor belts brought the pebbles towards three horizontal jaw crushers and a vertical cylinder crusher inside the building. The crushed pebbles were stored in a first concrete silo with four compartments inside the building and in a second silo (about 10 × 5.40 meters) provided with five hoppers at about 30 m from the building.
At the pebble factory of Pointe Saint Mathieu no remains witnessed the presence of a crushers building and a massive wall. Identifiable (cf.
The first silo (1) is about 10 meters long, 5 meters large and 8 meters high. The imprints of the wooden bars of the formwork on the concrete confirm that it is a typical work of the German masonry. The silo is provided with five pebble compartments, each superimposed to one hopper. The hoppers permitted the loading of pebbles on vehicles parked on an underlying loading way. The compartments were filled with pebbles and/or crushed pebbles by a possible conveyor belt mechanism of which concrete supports were still recognizable. From where the pebbles came remains a mystery. The silo is in a good state of preservation and does not present damages due to combats (
The absence of traces of railway lines on the loading way and around the silo suggested that the pebbles were loaded on trucks for a transport on short distances. Therefore, the Kieswerk was very likely to have participated in the construction of the Atlantic Wall fortifications of Pointe Saint-Mathieu (
A concrete barrack (2) about 5 × 3 meters is located at about 5 meters from the first silo. Its recent aspect and the impossibility to have a close look to its masonry let in doubt about whether it is contemporary to the first silo or built later. A possible second silo or barrack (3) about 5 × 2.5 meters on a private field and encircled by the vegetation was not accessible.
I am happy to have visited the vestiges of the Kieswerks of Camp Todt and of Pointe Saint-Mathieu. These op-
portunities have provided me with information about a non-secondary aspect of the construction of the Atlantic Wall and I hope that this article will stimulate other studies on this subject.
