20.1 The Kingdom of Norway has one of the longest coastlines in the world, facing the North Sea from the Skagerrak in the south and extending north beyond the Arctic Circle. A glaciated, mountainous territory, its recent economic history owes much to the rich oil and gas reserves within its sphere of influence. The country has a constitutional monarchy and the legal system is a blend of customary law, civil and common law traditions. The national currency of Norway is the Krone (NOK).
