German Gravel Mill Tréguennec

Organization Todt, who accounted for virtually all German construction works before and during the war, built a large factory in 1942 to crush stone at the French town of Tréguennec in Brittany.

The factory would provide cutting-edge for the building of the many bunkers along the Atlantic Wall. A railroad and roads were built, so the many tons of shards could easily be transported to the construction sites along the Atlantic Wall.

The factory continued production throught the war and was subsequently driven by a French company until 1948 where it was closed.
