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.
Gamlebyen Church
Gamlebyen Church is a private church, belonging to Oslo University Hospital and is also called "Oslo Hospital's" Church, located in the old town of Oslo, Norway. It is leased to the Diocese of Oslo of the Church of Norway and serves as the parish church for the Gamlebyen parish in Oslo. Up to 1925 it had the name Oslo Church, but when the city changed its name from "Kristiania" to "Oslo", the church got the present name. The present church building is listed in 1796 partly on the foundations of the Franciscan monastery church built around 1290. The church is located at the foot of the north-facing slope Ekeberg, across the street from the Gamlebyen Cemetery. The chapel at the cemetery is abandoned as a burial chapel and leased to the Ethiopian community in Oslo. At funerals, the church itself is now used instead.
