As it says in the Olympic Charter, the five-ringed symbol represents the union of the five continents and the meeting of athletes from throughout the world at the Olympic Games.. Baron Pierre de Coubertin, the founder of the modern Olympic Movement, conceived both the symbol and the flag.
The Olympic flag was first used in the 1920 Olympic Games in Antwerp, Belgium. The Olympic flag is paraded during the opening ceremony of each Olympic Games. At the end of an Olympics, the mayor of the host-city presents the flag to the mayor of the next host-city. The flag will remain in the town hall of the next host-city until the next Olympic Games, four years later.
