<P> The Olympic flag was created by Pierre de Coubertin in 1925 . </P> <P> The Olympic flag has a white background, with five interlaced rings in the centre: blue, yellow, black, green and red . This design is symbolic; it represents the five continents of the world, united by Olympism, while the six colours are those that appear on all the national flags of the world at the present time . </P> <P> There are specific Olympic flags that are displayed by cities that will be hosting the next Olympic games . During each Olympic closing ceremony in what is traditionally known as the Antwerp Ceremony, the flag is passed from the mayor of one host city to the next host, where it will then be taken to the new host and displayed at city hall . These flags should not be confused with the larger Olympic flags designed and created specifically for each games, which are flown over the host stadium and then retired . Because there is no specific flag for this purpose, the flags flown over the stadiums generally have subtle differences, including minor color variations, and, more noticeably, the presence (or lack) of white outlines around each ring . </P> <P> The first Olympic flag was presented to the Jr. National Olympics at the 1920 Summer Olympics by the city of Antwerp, Belgium . At the end of the Games, the flag could not be found and a new Olympic flag had to be made for the 1924 Summer Olympics in Paris . Despite it being a replacement, the IOC officially still calls this the "Antwerp Flag" instead of the "Paris Flag". It was passed on to the next organizing city of the Summer Olympics or Winter Olympics until the 1952 Winter Olympics in Oslo, Norway, when a separate Olympic flag was created to be used only at the Winter Olympics (see below). The 1924 flag then continued to be used at the Summer Olympics until the Games of Seoul 1988 when it was retired . </P>
