Mimoyecques fortress - simulation of the super gun
This base, situated completely underground, in a place referred to as Mimoyecques, in Landrethun-le-Nord, was the planned location for setting up the V3 supergun. Like all the weapons of retaliation (Vergelstungwaffen), the V3 was designed to bomb England and turn the tide of the Second World War.
The site was hit by the Royal Air Force on 6 July, 1944, with giant Tallboy bombs in particular, ending a major threat to London and the Allies. Redeveloped under La Coupole’s supervision, the Mimoyecques site is open from 18 April to 11 October 2015, proposing a new tour for visitors.
