Forteresse de Mimoyecques, Landrethun-le-Nord

Built between 1943 and 1944, Forteresse de Mimoyecques is the modern name for a Second World War underground military complex created by the forces of Nazi Germany. When you visit this museum, you can explore and discover a network of tunnels, partly destroyed just after the war on Churchill’s orders. Nevertheless, you will still find this an exciting and even eerie destination, especially considering this secret base was expected to be used for the installation of the giant underground V3 super gun.

Temperatures in the underground tunnels can drop quite low, so it is recommended that you bring a warm jacket. To find out how to plan a trip to Landrethun-le-Nord, use our trip itinerary maker.

  • Fascinating stuff, an underground WW2 bunker. Dark, dinghy (but still accessible), it's quite breathtaking. Only takes about 45 minutes to an hour to get around it so don't plan a day out.
  • Very interesting place to visit. The tunnels are where the V3 bombs were made and launched. It's very cold in the tunnels so take a coat. There are information boards with English translation. The staff were very helpful.
