Oslo is a municipality, as well as the capital and most populous city in Norway. It was established on January 1, 1838. Founded around 1048 by King Harald III of Norway, the city was largely destroyed by fire in 1624. The city was moved under the reign of Denmark–Norway's King Christian IV. It was rebuilt closer to Akershus fortress, as Christiania (briefly also spelt Kristiania). In 1925, the city reclaimed its original Norwegian name, Oslo. The diocese of Oslo is one of the five original dioceses in Norway, which originated around the year 1070.
Oslo is the cultural, scientific, economic and governmental centre of Norway. The city is also a hub of Norwegian trade, banking, industry and shipping. It is an important centre for maritime industries and maritime trade in Europe.
Oslo's cityscape is being redeveloped as a modern city with various access-points, an extensive metro-system with a new financial district and a cultural city. In 2008, an exhibition was held in London presenting the award-winning Oslo Opera House, the urban regeneration scheme of Oslo's seafront, Munch/Stenersen and the new Deichman Library. Most of the buildings in the city and in neighbouring communities are low in height with only the Plaza, Postgirobygget and the highrises at Bjørvika considerably taller.
