Norway is a Nordic country located on the western part of the Scandinavian Peninsula. Its capital is Oslo. Norway is world-famous for its fjords—deep, narrow inlets of the sea with high cliffs, carved by glaciers during the last Ice Age. The Sognefjord is the largest and deepest of these. The country has an incredibly long and rugged coastline, which includes over 50,000 islands. Norway also administers the Arctic archipelago of Svalbard. Much of the country lies north of the Arctic Circle, where the Midnight Sun can be seen in summer and the Northern Lights (Aurora Borealis) in winter. Norway is one of the world's largest exporters of oil and seafood and consistently ranks as one of the happiest and most developed countries in the world.
