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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
