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 Museum
The museum was first founded in 1905 as the association "Det gamle Christiania". Initiator and committee leader until 1912 was architect Fritz Holland (1874-1959). A committee members included Bishop of Oslo Anton Christian Bang, architects Torolf Prytz and Harald Olsen, artist Eilif Peterssen and military officer Thomas Heftye. The museum moved into the main building at Frogner Manor in 1909.
