France, Pas-de-Calais, Eperlecques, The Eperlecques Blockhouse, The Eperlecques Blockhouse (also known as the Watten Bunker) is a World War II bunker. It was built by Nazi Germany between 1943 and 1944 to serve as a launch site for V2 rockets targeting London and southern England. It was constructed by forced labourers from concentration and labour camps, as well as by Frenchmen who had been conscripted. The blockhouse was never completed due to repeated bombing by the British and Americans. Translated with DeepL.com (free version)
