Crown Prince Olav and Crown Princess Märtha of Norway (glittering in the Norwegian Emerald Parure) celebrate his 50th Birthday at a grand Gala Dinner at the Akershus Fortress in Oslo on this day in 1953. This was one of the first glittering events in Norway after WWII, and one of the last for the Crown Princess, who passed away the following year. Crown Prince Olav succeeded his father, King Haakon VII, in 1957.
