Svalbar is an archipelago in the Arctic Ocean north of mainland Europe, about midway between Norway and the North Pole. It consists of a group of islands ranging from 74° to 81° North, and 10° to 35° East. The archipelago is the northernmost part of Norway. Three islands are populated: Spitsbergen, Bjørnøya and Hopen. The largest settlement is Longyearbyen. The Svalbard Treaty recognises Norwegian sovereignty over Svalbard and the 1925 Svalbard Act makes Svalbard a full part of the Norwegian Kingdom.
