St. Hanshaugen
To the southeast of the park is Oslo’s oldest building – Aker Kirke, built around 1100, but restored from ruins around 1860, and then again in the 1950s in a more authentic style. Next to the church is the cemetery Vår Frelsers gravlund, created in 1808 as a result of the great famine and cholera epidemic of the Napoleonic Wars. The nearby area around Damstredet and Telthusbakken is interesting since it retains the small town character of Oslo in the first part of the 19th century.
Hieronymus Heyerdahl (1867–1959)
He served on the City Council 1911-19 and 1923-25 and as mayor of Oslo from 1911 to 1914. At the end of his term in office, he developed the plans to build a new Oslo City Hall ("Oslo rådhus"). Heyerdahl launched the fundraising campaign for a new Oslo City Hall in 1914. Construction started during September 1931 and officially the facility opened in May 1950.
