Minnehallen or The hall of remembrance was commissioned by the Norwegian parliament after World War I to commemorate the fallen Norwegian sailors of the war. It was unveiled by king Haakon VII and was later converted to the national monument commemorating fallen sailors of both World War I and World War II. The interior of the hall is visited by some 20,000 people every year. The monument itself is a pyramid of locally quarried rock and is designed by two architects from Oslo, Andreas H. Bjercke and Georg Eliassen.
