In which European capital would you find this building?

The Stockholm City Hall (Swedish: Stockholms stadshus or Stadshuset locally) is the building of the Municipal Council for the City of Stockholm in Sweden. It stands on the eastern tip of Kungsholmen island, next to Riddarfjärden's northern shore and facing the islands of Riddarholmen and Södermalm. It houses offices and conference rooms as well as ceremonial halls, and the luxury restaurant Stadshuskällaren. It is the venue of the Nobel Prize banquet and is one of Stockholm's major tourist attractions.

In 1907 the city council decided to build a new city hall at the former site of Eldkvarn. An architectural contest was held which in the first stage resulted in the selection of drafts by Ragnar Östberg, Carl Westman, Ivar Tengbom jointly with Ernst Torulf, and Carl Bergsten. After a further competition between Westman and Östberg the latter was assigned to the construction of the City Hall, while the former was asked to construct Stockholm Court House.

Östberg modified his original draft using elements of Westman's project, including the tower. During the construction period, Östberg constantly reworked his plans, resulting in the addition of the lantern on top of the tower, and the abandonment of the blue glazed tiles for the Blue Hall.
