St Ouen’s Bay being the longest shallow sandy bay, it was always going to be considered as the most likely Allied landing beach to re-take the Island. Around the Corbière headland at the southern end of the bay, the Germans constructed a number of coastal defence bunkers creating a network to prevent the formation of a beachhead in the event of a landing.

A number of these bunkers have not only survived, but are preserved in the care of the Channel Islands Occupation Society. Amongst what would have been minefields and defence positions with flame-throwers and machine guns, a fortress mortar was housed in one of the bunkers and a captured 1918 vintage French 10.5cm gun in another, overlooked by a naval artillery observation tower.
