Battery Moltke was an uncompleted World War II coastal artillery battery. It was constructed by Organisation Todt for the Wehrmacht during the Occupation of the Channel Islands. The battery structures include bunkers, gun emplacements and the Marine Peilstand 3 tower, which are located on Les Landes, a coastal heathland area at the north end of St Ouen's Bay. The bunker was left unfinished at the end of the war, when completed there would have been an M132 Command Bunker like at Battery Lothringen and the main armament would have consisted of 4x15 cm SK C/28.The primary purpose of this battery would have been the defence of St Ouen's Bay in the event of an amphibious assault by the Allies, although Jersey's entire coastline would have been within range of the guns, as would the stretch of water between Jersey and Sark.
Four captured French 155mm cannons were located at Moltke. One of the original guns can be seen there today. The exterior areas of the site are accessible around the year. The Channel Islands Occupation Society operates some of the bunkers as a museum. One may visit the gun emplacements at any time. Two cannon barrels recovered from the foot of the near-by cliffs are on display in one of the emplacements. These two salvaged barrels were not originally located at Moltke.
References:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
