17th century quarrying of granite.
1877 iron mine opened.
1962 iron mine closed.



The Musée des Mines et des Carrières à Flamanville (Museum of Mines and Quarries in Flamanville) is dedicated to different mining and quarrying operation in the small village at the channel. A central exhibit is a video of a boat being loaded with wagons from the mine, reminiscent of the film "la maison sous la mer" (the house under the sea) shot in Flamanville. The underwater mine was located in Diélette. Three hundred miners, carters and blacksmiths were mining the iron ore. It was one of the most famous mines in France, probably because it was under the sea. This had a main drawback though, there was a lot of water in the mine and dewatering the mine was the main problem and made the mine unprofitable much earlier than other iron mines.

The mining started the 17th century with the quarrying of granite. The Flamanville granite was used for the needle of the Obelisk on the Place de l'Hôtel de Ville in Cherbourg, the cobblestones of Place de la Concorde in Paris, and the construction of the ports of Querqueville, Homet and Pelee Island. In the middle of the 19th century the need for granite diminished, but there was also iron ore, and so the exploitation of iron ore replaced that of granite. As the sea, near the outer jetty, two 150 m deep shafts were sunken in 1877.

Today the site is occupied by a nuclear power plant, one of the blind spots on Google Earth. France is extremely dependent on its nuclear power plants, a fact which became obvious during the 2022 energy crisis. The Flamanville nuclear power plant has an area of 120 ha, half of which was reclaimed from the sea. With two production units with a power of 1.3 GW each, EDF Flamanville produces 4% of the electricity in France, and meets 69% of the region's electricity needs.

The Mines and Quarries Museum, located in the town center of Flamanville, south of the curch. It occupies the right wing of the Le Rafio, the concert hall and arts center of Flamanville.
