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 Cathedral
Oslo Cathedral is located at Stortorvet square north/north-east of Karl Johans gate, between Kirke gate and Dronningens gate. The Cathedral's lower end is surrounded by the Bazaar ("Basarene ved Oslo domkirke"), a curved long building with a tower covered in green copper like the Cathedral. Integrated with Basarene is the Fire Watch ("Brannvakten") which served as Oslo's main fire station from 1860 until 1939, when today's main fire station at Arne Garborgs plass was opened. The Cathedral, Basarene and Brannvakten are all built in red brick. Both Basarene and Brannvakten were built between the years 1840-1859 from the plans of City Architect, Christian H. Grosch.
