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.
