[4] The cathedral is a double-nave basilica that has a free-standing bell tower next to the main building.

The entrance consists of two copper-clad doors surrounded by fields in natural concrete under a gable roof.

The square campanile (bell tower) is at the church's southwest corner, and it is approximately 60 metres (200 ft) tall.

Behind the church's main entry doors to the west, there is a spacious rectangular foyer which leads into the sanctuary.

[9][10] In 1841–42, the church was heavily renovated and large portions being rebuilt in essentially the same style.

This church burned down during the bombing of Molde on 29 April 1940 (during World War II).
