Festival of Britain

The Festival of Britain was a national exhibition which opened in London in May 1951 to boost national morale, as Great Britain was still recovering from World War II. The Seventh Doctor and Ace visited the Festival after defeating the Timewyrm. (PROSE: Timewyrm: Exodus) The Eighth Doctor also visited the Festival and saw his past self, but neither recognised the other. (PROSE: Endgame)

The Second Doctor, Jamie McCrimmon, and Zoe Heriot visited the Festival and encountered a Vardan. (AUDIO: The British Invasion)

The exhibition was still popular in August 1951. (TV: The Temptation of Sarah Jane Smith)

In an alternate timeline in which Germany won the war, the Festival of Britain was a celebration of ten years of Nazi victory. The Seventh Doctor and Ace visited this version of the Festival, where they realised that history had been altered, and went to work preventing this timeline. (PROSE: Timewyrm: Exodus)
