During the Viking Age, the area was part of Viken. Oslo was founded as a city at the end of the Viking Age in 1040 under the name Ánslo, and established as a kaupstad or trading place in 1048 by Harald Hardrada. The city was elevated to a bishopric in 1070 and a capital under Haakon V of Norway around the year 1300.
Oslo is Norway's capital and largest city, with 700,000 citizens in the city proper and about 1.5 million inhabitants in greater Oslo. It is in the East of the country in the Oslofjorden fjord, extending over an inlet of the Skagerrak strait. It is spaciously laid out and surrounded by green hills and mountains and includes 40 islands and 343 lakes. Oslo offers ski slopes for alpine skiing and ski trails for cross-country skiing in the winter. In the summer, the temperature in Oslo may make it comfortable to swim. There are several well-visited beach resorts. Oslo is one of the world's northernmost capitals and so gets only 6 hours of sunlight in the winter.
