U.K. National Archives
This summer London will become the first city to officially host the Olympic Games three times.
The U.K. National Archives hold records from the first summer games in Greece, in 1896, right up to archived websites from 2012 - including files from 1908 and 1948 when London previously hosted the games.
1908 was the first year a special stadium was built and the 1948 games were the first to be broadcast on television. Browse the timeline to see what else you can discover about the history of the modern Olympic and Paralympic Games.
