Oslo is the capital city of Norway. According to the Norse lore, Oslo was founded around 1048 by king Harald Hardråde.
It occupies an arc of land at the northern end of the Oslofjord. The fjord, which is nearly bisected by the Nesodden peninsula opposite Oslo, lies to the south; in all other directions Oslo is surrounded by green hills and mountains. There are 40 islands within the city limits, the largest being Malmøya (0.56 km²), and scores more around the Oslofjord. Oslo has 343 lakes, the largest being Maridalsvannet (3.91 km²). This is also a main source of drinking water for large parts of Oslo. The highest point is Kirkeberget, at 629 m. Although the city's population is small compared to most European capitals, it occupies an unusually large land area. Its boundaries encompass many parks and open areas, giving it an airy and often very green appearance.
