Grünerløkka

Grünerløkka is both a borough and a neighbourhood of Oslo, which became part of the city (then Christiania) in 1858. It is named after Friedrich Grüner (1628–1674), who served as chief administrator and master of the mint in Christiania. The industrialist Thorvald Meyer bought parts of the area in 1861, and factories were built here because of the nearby Akerselva River. Traditionally a working-class district, Grünerløkka has increasingly undergone gentrification since the late 20th century.

The heart of the neighbourhood is Olaf Ryes plass, a park square named after the Norwegian-Danish general Olaf Rye (1791–1849) that was still an open field well into the 1880s. Its main streets include Markveien, Thorvald Meyers gate and Toftes gate, which around 1900 were among the most populous streets in the city. The area belongs to the parish of Paulus Church. Other landmarks listed for the borough include Birkelunden, Sofienberg Park and the Foss Brewery.
