Church of Our Lady of Trondheim

Nidaros Cathedral in Trondheim is the most important church in Norway being the burial place of its patron saint: St. Olav. Built from the 11th to the 14th century, in Romanesque and Gothic style, it suffered extensive damage during a fire in 1531 but was completely rebuilt and served, until 1908, as Norway's coronation church.

The hospital church, with its characteristic tower and roof, stands out well from the old town on Hospitalsløkkan. It was built in 1705 and replaced an earlier medieval church on the same site. It is one of the first octagonal-plan churches in Norway, designed by Johan Christoffer Hempel of the Reformed Netherlands.

The Bakke Church is an octagonal church built in 1714-1715 by the architect J. C. Hempel. It was completed in 1715 and was originally called Anne Dorothea Church, after the wife of Bishop Peder Krog. The church has a baroque appearance with a high spire. As the only building in Bakklandet, the church was spared during the Swedish siege in 1718. Together with the Hospitalskirken, it is one of the few well-preserved buildings from the early 18th century in Trondheim, where fires and alterations have changed the rest of the town's character.
