[1] The grave chapel was constructed in granite and clay stone and was designed by architect Alfred Christian Dahl (1857–1940).

Most of the others were killed in air crashes during Allied landings, 43 lives being lost on Liberation Day alone (10 May 1945).

The presiding officer was by General Otto Ruge, who had commanded the Norwegian Army at the time of the German invasion in April 1940.

Opposite to the cross the citizens of Oslo erected a memorial to Commonwealth servicemen who died on Norwegian soil during the liberation of Norway.

The memorial is in form of a kneeling figure of a mourning naked woman and was unveiled during June 1960 by King Olav V of Norway.
