Fortress of Mimoyecques, Landrethun-le-Nord

The Fortress of Mimoyecques is the modern name for a Second World War underground military complex built by the forces of Nazi Germany between 1943 and 1944. It was intended to house a battery of V-3 cannons aimed at London, 165 kilometres away. Originally codenamed Wiese or Bauvorhaben 711, it is located in the commune of Landrethun-le-Nord in the Pas-de-Calais region of northern France, near the hamlet of Mimoyecques about 20 kilometres from Boulogne-sur-Mer. It was constructed by a mostly German workforce recruited from major engineering and mining concerns, augmented by prisoner-of-war slave labour. ()
