Holmenkollen Chapel is a small, dark-painted wooden church set in the forest near the ski jump, consecrated in 1903. It is quiet and easy to miss — which is part of its appeal. The surrounding pine trees and the simple Norwegian timber construction give it a stillness that the busier tourist attractions nearby lack.
The chapel is used for regular services and is particularly atmospheric in winter, surrounded by snow. Worth a brief detour if you're already walking the trails above Holmenkollen station.
