Oscarshall

Oscarshall in Oslo, Norway is a mid-19th-century summer palace built for the Swedish–Norwegian royal household. Erected between 1847 and 1852 in a neo‑Gothic manner with elements associated later with Norway’s National Romantic tastes, the site became an important example of that architectural current in the country and a royal cultural retreat on the Bygdøy peninsula.

Construction and early royal ownership began in the 1840s when the palace was commissioned by King Oscar I and Queen Joséphine and completed in 1852. In 1863 ownership passed from King Carl IV to the Norwegian state. The building took on a public cultural role when King Oscar II opened it as a museum in 1881. Following the First World War era, in 1929 authorities decided the palace should serve as the residence for Crown Prince Olav and Princess Märtha; the plan did not go ahead because of financial difficulties and political resistance, and the couple instead acquired the estate Skaugum from Fritz Wedel Jarlsberg.

Throughout the 20th and 21st centuries the palace remained state property and was kept available to the sovereign. A thorough restoration between 2005 and 2009 reinstated the interior colours and furnishings to their mid-19th-century appearance, after which the building was reopened for guided visits in the summer season. A gallery bearing Queen Joséphine’s name was established on the grounds in 2013, inaugurated by Queen Sonja and initially displaying graphic prints including works by the Queen herself. After a period in the 1990s when the palace was remodelled and opened to the public as a museum, the site continued to be maintained as a state-held royal property; in 2022 the summer palace was closed to visitors because of extensive construction work in the surrounding park.
