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.
Oslo City Hall
Oslo City Hall was officially opened on 15 May 1950, as part of the city's 900-year anniversary. Three musical compositions were written in connection with the celebrations, written by  Ludvig Irgens-Jensen, Eivind Groven and Karl Andersen.
