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.
Alvøen
Alvøen is the site one of Norway’s oldest industrial communities and one of the best preserved industrial locations. In 1626, King Christian IV of Denmark granted the right to establish a gunpowder mill on the site. The mill was destroyed by fire in 1733, but rebuilt. Didrich Jansen Fasmer (1706-1770) improved it and built another gun mill in the 1760s. Towards the end of the 1700s, Alvøen became an industrial site with working houses attached to the factories. Later it started production of saltpeter, linseed oil and paper. Hendrik Jansen Fasmer (1766-1836) founded the paper mill during 1797. In 1858, Hendrik Fasmer (1835–1930) built a new papermill in Alvøen and from the late 1800s the production was concentrated on finer grades in different blends of cloths and cellulose. Alvøens Papirfabrik A/S manufacturing paper in Alvøen until stopped production in 1981. At that time, it was the oldest paper mill in the country. The specialty was finer paper for documents and from 1908, supplier of paper for Norwegian banknotes.
Alvøen Manor was the main residence of the owners of the paper factory of Alvøen. Alvøen Manor was originally built as a countryside retreat for members of the Fasmer family in 1797. Eventually the roccoco main building was surrounded by several gardens. 
Alvøen Manor and the factory were opened as a museum ("Alvøen Hovedbygning") in 1983, as a branch of the . It is now managed by the Bergen City Museum. The site includes Alvøen Manor together with some forty worker cottages and production buildings dating from the 1800s.
