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
In 1624, all of old Oslo burnt to the ground. King Christian IV decided that the city should not be rebuilt at the same location and instead be built to the north of Akershus Fortress. The new city had wide streets at right angles. Building space for a town hall was made available between "Rådhusgaten" and "Øvre Slottsgate". What is today referred to as the old City Hall ("Gamle rådhus") was finished in 1641. The building still exists at Nedre Slottsgate 1. The building fell into decay and by 1733 a building at "Rådhusgaten 7" was selected to be a new City Hall.
