Battery Moltke or Batterie Moltke is an uncompleted World War II former coastal artillery battery in St Ouen in the north west of Jersey. 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 4x 15 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.
Gun emplacements
Four captured French Canon de 155mm GPF, known as the 15.5 cm K 418 by the Germans, were located at Moltke. One of the original guns can be seen there today. These guns could be fully rotated to fire in any direction. They had a maximum range of around 19,500 m. The French guns were intended to be temporary until more modern 15 cm SK C/28 guns could be delivered; these guns never arrived.
MP3 tower
The Marine Peilstand 3 tower, or MP3 tower, is one of nine planned towers, in Jersey, for use in observing targets at sea. It is similar to the other two completed towers of this type. The tower is located at the top of a steep sloping, west-facing cliff. It has seven floors including a windowless underground floor and the walled top deck where a Seetakt radar was located. The land-side entrance is on the third level.
Ringstände
Examples of Ringstände can be found at the battery site. These are a type of defensive fighting position known as Tobruk by the Allies, and are small bunkers constructed from concrete with an aperture on the top which was used to mount a turret from an otherwise obsolete tank.
Present day
In 2013, the exterior areas of the site are accessible at all times. 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 nearby cliffs are on display in one of the emplacements. These two salvaged barrels were not originally located at Moltke.
