In the Bay of Audierne, between the Pointe de La Torche and the port of Penhors, the Tréguennec blockhouses were built in 1942 by the Germans to construct the "Atlantic Wall", building thousands of bunkers along the French west coast to prevent the Allies from invading from England. These blockhouses were built using the Ero Vili, a 12-kilometre-long pebble barrier up to 8 metres high. This natural barrier was used as a source of raw material by the Germans to build many of the blockhouses on the Atlantic Wall. They built a pebble crushing plant at Tréguennec, where you can see the remains of around 1 million tonnes of pebbles that were crushed. To reach the blockhouses, cross the Vent Solaire road, which runs along the entire coastline, and take some lovely photos of the blockhouses at the end of the day, with the sun setting over the long white sandy beaches.
