Marine Küstenbatterie Longues-sur-Mer

Excavation for this battery began in autumn 1943. This battery was part of the Atlantic wall. When the Allies invaded France nine months later in June 1944, the four 152 mm. guns had just been mounted in their pillboxes. In addition to the firing positions, there was a fire control bunker located 500 meters forward of the gun positions.

In the days leading up to the invasion, this battery was heavily bombed, but none of the guns were hit. The battery was able to return fire at approximately 0537 on 6 June, 20 minutes before sunrise, when it targeted HMS Bulolo, flagship of Force G on D-day. The ship avoided the fire and the battery then came under heavy fire from four more warships. It was approximately dinner time when the last round was fired from a now defeated battery.

Today, this battery is the only one in Normandy with the original guns still in place in the bunker.
