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.
Oude Kerk, Amsterdam
The Oude Kerk (English: Old Church) is Amsterdam’s oldest building and oldest parish church, founded circa 1213 and consecrated in 1306 by the bishop of Utrecht with Saint Nicolas as its patron saint. After the Reformation in 1578 it became a Calvinist church, which it remains today. It stands in De Wallen, now Amsterdam's main red-light district. The square surrounding the church is the Oudekerksplein.
