German battery at Longues-sur-Mer, a major remnant of the Atlantic Wall

By showing you the 4 concrete casemates, 3 of which still have their 150 mm guns, as well as the observation posts located on the cliff, I will tell you the whole story of one of the most impressive remains of the Atlantic Wall, from its construction from 1943 until its capture by the British, passing through its action on June 6, 1944.
