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 Citadelle of Quebec is an active military installation and official residence of both the Canadian monarch and the Governor General of Canada. It is located atop Cap Diamant, adjoining the Plains of Abraham in Quebec City. The citadel is the oldest military building in Canada, and forms part of the fortifications of Quebec City, which is one of only two cities in North America still surrounded by fortifications, the other being Campeche, Mexico.
The first fortifications in Quebec were built by the Governor General of New France Louis de Buade, and completed just in time for the Battle of Quebec in 1690.
After the British conquest in the second half of the 18th century, the problem of Quebec City's defences grew more acute.
