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.
Oslo Stock Exchange
The over 180-year-old stock exchange building has been the subject of many long debates about how the building should be managed and designed over the years. Several of Christiania's (the name of Oslo between 1624 and 1925) best known business men fought for years to get approved and funded the construction of a stock exchange in Christiania, the capital of Norway from 1814.
