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.
Trondheim Cathedral School
There is great dispute regarding the actual founding date of the Trondheim Cathedral, but the most common theory is that the school was founded in approximately 1152 and is hence the oldest school in Norway. The oldest part of the present school is the Harsdorff building (Munkegata 8), which was completed in 1786. The building is named after its designer Caspar Harsdorff, a royal Danish architect. Originally though, the school's design was submitted by a local architect/organist/fireman, but upon review by the Danish king it was turned down and his royal architect assigned with designing the school. It was funded by Thomas Angell (1692–1767), a Trondheim merchant. Festival Hall on the second floor has two marble reliefs by noted Danish sculptor Bertel Thorvaldsen (1770–1844). In 1920, the school underwent a major expansion, with buildings designed by Norwegian architect Carl J. Moe (1889–1942).
