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.
Wessels plass
Originally on the site was a knoll with a house surrounded by a garden. The Parliament of Norway Building was completed in 1866, ad in 1873 Oslo municipality bought the knoll. It was demolished around 1880 to give room for a park-like square. Named Stortingspladsen ('The Storting Square'), it was given its current name in 1891. It was named after Johan Herman Wessel, and a bust of him was raised here in 1891. A statue of Johan Sverdrup was raised in 1964. Under the square is a walking tunnel between the Parliament of Norway Building and office buildings across the street.
