The is one of several impressive sites from World War Two in northern France, connected to the…read moredevelopment and construction of the V2 rocket-bombs by the Nazi regime.
The site at Éperlecques was designed and built by the Todt Organisation, initially using voluntary labour, but later using large numbers of forced labour. Essentially, the site consisted of a series of enormous bunkers, intended to include a liquid oxygen plant for the V2 rocket propellant, an assembly plant to load on the explosive warhead, and a firing facility. 35,000 labourers worked at the site between 1943 and 1944.
However, the Allies were alerted to its existence before it was completed. A series of bombing raids, using the then newly-developed 'Tallboy' bunker-busting bombs, caused severe damage to the facility (as well as huge loss of life to the construction workers). Thereafter, V2 construction was moved to a new site at La Coupole, and the bunker was used only to manufacture liquid oxygen.
The site to-day is surrounded by woods, and the most of the tour takes place out of doors: displays explain the concept of forced labour, the Todt organisation, and the background to the V1 and V2 rockets.
But the highlight is the bunker itself. It's a huge construction - over 90,000 tonnes of concrete were used, and the Blockhaus rises over 25m from the ground. It's a sobering thought to think that it is only a third of its planned size. The atmosphere is chilling, almost eerie: much of the lower section is under water, as without pumps the groundwater has flowed back in. The impact of the tallboy bombs is made clear by huge holes in the bunker roof and masses of twisted metal reinforcement. Part of the interior is accessible: a video presentation in the largest chamber inside describes the construction and operation of the facility, and the lives (and deaths) of the labourers.
The tour finishes with outdoor displays of a V1 launch pad and other military items. There's no cafe but there is a small shop on site, selling books and momentos. There is specially reserved (level and firm) parking for motorcycles, and motorcyclists get a reduction of 1EUR on the entry fee.
The whole site is now a French national memorial, dedicated to the victims of forced labour.
