Oslo is the capital and largest city of Norway, home to about 724,000 people in the municipality and some 1.1 million in its urban area. It occupies an arc of land at the northern end of the Oslofjord, with wooded hills, known as Marka, rising behind it, and around two-thirds of its area is protected forest, hills and lakes.
Founded at the end of the Viking Age and rebuilt as Christiania after a fire in 1624, the city took back its old name in 1925. Visitors come for the reborn waterfront, where the Opera House and the MUNCH museum stand in Bjørvika, the Vigeland sculptures in Frogner Park, the museums of the Bygdøy peninsula, ferries to the fjord islands and the ski jump at Holmenkollen. Apartments in the centre or Grünerløkka suit short city breaks, while family-sized flats in Frogner or Majorstuen give more room for longer stays. Summer days are long, with more than 18 hours of daylight at midsummer.
The city centre, Sentrum, is built around Karl Johans gate, the main pedestrian street that runs from the Royal Palace towards the Central Station, with the Parliament and the National Theatre along the way. It suits a short first visit, with the harbour and most museums on foot. On the waterfront, Aker Brygge and Tjuvholmen, built on the site of a former shipyard, have modern flats by the water, while Bjørvika and Sørenga, east of the centre, are new harbourside districts around the Opera House and MUNCH.
Grünerløkka, a traditionally working-class district beside the Akerselva river that has gentrified since the late 20th century, is known for its cafés and restaurants and appeals to younger travellers. Frogner and Majorstuen, in the West End near Frogner Park, are calm residential areas with metro stations close by, good for families and longer stays. Grønland, just east of the Central Station, is lively and known for its varied food.
Oslo's harbour has been transformed in recent decades. The Oslo Opera House, home of the Norwegian National Opera and Ballet, opened in Bjørvika in 2008, and its roof slopes down to ground level so that anyone can walk up it for views over the city and the fjord. Next door, the MUNCH museum, dedicated to the life and work of Edvard Munch, moved into its new building in 2021. Across the harbour, Akershus Fortress, a medieval castle thought to have been begun in the late 1290s under King Haakon V, guards the waterfront; it has been a royal residence, a military base and a prison.
The Royal Palace, built between 1824 and 1848, stands at the top of Karl Johans gate. In Frogner Park, the city's largest park and open to the public at all times, Gustav Vigeland's sculpture installation has been taking shape since 1924. The Nobel Peace Prize is awarded in Oslo each year, and the Nobel Peace Center tells its story.
The Bygdøy peninsula, on the western side of the city, is a green recreation area and one of the most sought-after residential districts in Norway. It is also home to several museums, including the Kon-Tiki Museum, devoted to Thor Heyerdahl's expeditions, the Norwegian Museum of Cultural History, an open-air collection of buildings moved from towns and rural districts, and the Norwegian Maritime Museum. Bus 30 runs there from the centre, and between April and October a public ferry also crosses from Aker Brygge.
Forty islands lie within the city limits, and ferries connect several of them with the centre. Hovedøya, a small island with the ruins of a Cistercian abbey opened in 1147, is a popular summer escape. To the north, Nordmarka, the largest part of the Marka forest belt, is crossed by trails for hiking and cycling in summer and for skiing in winter, and the lake of Sognsvann, just north of the city, is a favourite starting point.
Oslo was founded as a town around 1040 under the name Ánslo and established as a trading place in 1048 by Harald Hardrada. It became a bishopric in 1070 and the capital under Haakon V around 1300, but long unions with Denmark later reduced its importance. After fire destroyed the town in 1624, King Christian IV had a new city built closer to Akershus Fortress and named it Christiania in his own honour.
The city served as the capital during the union between Sweden and Norway from 1814 to 1905, and many of its public buildings date from that century, including the Royal Palace, the Storting parliament building of 1861 to 1866 and the National Theatre of 1899. The spelling later changed to Kristiania, and on 1 January 1925 the original name, Oslo, was restored. In 1948 Oslo merged with Aker, the municipality that surrounded it, and in recent years the city has grown quickly and become more international.
Holmenkollen, a hill rising to about 500 metres in the north-west of the city, has been a ski area since the late 19th century and its famous jump has hosted competitions since 1892; the Holmenkollen line of the metro runs right up to it. Drøbak, on the narrow Drøbak Sound about halfway down the inner fjord, is close to the Oscarsborg fortress, where the German cruiser Blücher was sunk in April 1940 at the start of the invasion of Norway.
Fredrikstad, a port city in Østfold county, is known for the old fortified town on the east bank of the Glomma river, remarkably well preserved. Closer to home, the Oslofjord stretches for about 120 kilometres to the south, and boat trips, island ferries and walks along the shore are easy ways to see it. In winter the metro still reaches Holmenkollen and the forest edge, so a rented apartment works well as a base in every season.
Oslo Airport (OSL), at Gardermoen about 35 kilometres north-east of the city, is the main gateway. The Flytoget airport express train reaches Oslo Central Station in about 20 minutes, and airport coaches serve the city and other towns. Sandefjord Torp Airport, about 119 kilometres to the south, is used mainly by leisure and low-cost airlines.
Public transport is extensive, with the five-line Oslo Metro, a six-line tram network, eight commuter rail lines, buses and ferries, and most of the ferry fleet has been electrified. The metro climbs to Holmenkollen and the forest edge, trams serve the inner districts and boats link the islands and, in season, Bygdøy. The centre is compact, and the city has an extensive network of bicycle lanes. A car is not needed for a city stay; it is mainly useful for exploring the countryside beyond the fjord.
Oslo has a humid continental climate, with some of the warmest summers in Norway and fairly cold winters. Because of its northern latitude, daylight varies enormously, from more than 18 hours at midsummer, when it never gets completely dark at night, to around six hours in midwinter. Winter and spring are the driest seasons, while summer and autumn are the wettest.
June to August is the most popular time, with long evenings for the waterfront, the islands and the forest trails; July 2018, a record month, averaged daily highs of 29°C, but most summers are milder. In January about three days in four stay below freezing, and snow turns Nordmarka and Holmenkollen into ski country. Spring and autumn are quieter and fresh, good for museums and city walks. Whatever the season, pack layers and a rain jacket, and in winter plan around the short days.
For a first visit, the centre around Karl Johans gate and the harbour districts of Aker Brygge, Tjuvholmen and Bjørvika keep the main sights within walking distance. Grünerløkka suits younger travellers who like cafés, while Frogner and Majorstuen are calm residential areas that work well for families.
June to August brings the warmest weather and very long days, with more than 18 hours of daylight around midsummer. May and September are quieter and fresh. Winter is cold, with short days, but it is the season for skiing in Nordmarka and at Holmenkollen.
Oslo Airport (OSL) at Gardermoen is about 35 kilometres north-east of the city. The Flytoget express train reaches Oslo Central Station in about 20 minutes, and airport coaches also run into the city.
Two or three days cover the waterfront, the Opera House and MUNCH, Akershus Fortress, Frogner Park and the Bygdøy museums. With four or five days you can add island ferries, a hike in Nordmarka, Holmenkollen and a trip down the fjord to Drøbak.
No. The metro, trams, buses, commuter trains and ferries cover the city, the islands and the forest edge, and the centre is compact enough to walk. A car is only worth it for touring the countryside beyond the Oslofjord.
Yes. Children enjoy walking on the Opera House roof, the open-air museum and Kon-Tiki on Bygdøy, Frogner Park, island ferries and the forest lakes. A flat in a residential district such as Frogner or Majorstuen gives space and a kitchen, which helps keep costs and routines under control.
Yes. Under Norway's Owner Section Act, a whole flat in a building owned as sections may be let short-term, meaning up to 30 consecutive days, for no more than 90 days a year; the building's bylaws can set the limit between 60 and 120 days. Housing cooperatives have their own rules. Check the current rules before booking or letting.
Oslo is known for its fjord setting, the Opera House with its walkable roof, Edvard Munch's art, Vigeland's sculptures in Frogner Park, the Bygdøy museums, the Holmenkollen ski jump and the forests that surround the city. The Nobel Peace Prize is also awarded here every year.
