Old Aker Church
The church was built over the former site of the Akerberg mines ("Akersberg gruve"), an ancient silver mine which was in use since the early Viking era. The mines are mentioned in the 1170 "Historia Norvegiae". The existence of these former mines must have been the inspiration for a number of local stories about the church having hidden silver treasures and even dungeons with dragons.
Old Aker Cemetery () is the cemetery of Old Aker Church. Like the church, the cemetery dates back to the Middle Ages. The cemetery is located adjacent to the newer Cemetery of Our Saviour, which was established in 1808. Several notable people are interred in the cemetery.
Storting building
Following the establishment of the Parliament of Norway in 1814, which had happened at a private home belonging to Carsten Anker in Eidsvoll, the newly established legislature started meeting at Christiania lærde Skole at Tollbodgaten and Dronningsgate. From 1854, the legislature started using the grand hall at the Royal Frederick University. However, proposals of an own parliament building had arisen. The parliament voted down a government proposal to create such a building in 1833, but in 1836, the work to establish a permanent building started. Twelve lots in central Oslo, located between the Royal Palace and Oslo East Station. The government decided to build in the Palace Park, and this was passed by the parliament. However, instead the government chose to purchase the current lot instead. This was approved by parliament in 1857.
