The Olympic Games ceremonies of the Ancient Olympic Games were an integral part of these Games; the modern Olympic games have opening, closing, and medal ceremonies. Some of the elements of the modern ceremonies date back to the Ancient Games from which the Modern Olympics draw their ancestry. An example of this is the prominence of Greece in both the opening and closing ceremonies. During the 2004 Games, the medal winners received a crown of olive branches, which was a direct reference to the Ancient Games, in which the victor's prize was an olive wreath. The various elements of the ceremonies are mandated by the Olympic Charter, and cannot be changed by the host nation. This requirement of seeking the approval of the International Olympic Committee (IOC) includes the artistic portion of opening and closing ceremonies.
The ceremonies have evolved over the centuries. Ancient Games incorporated ceremonies to mark the beginning and ending of each successive game. There are similarities and differences between the ancient Olympic ceremonies and their modern counterparts. While the presentation of the Games has evolved with improvements in technology and the desire of the host nations to showcase their own artistic expression, the basic events of each ceremony have remained unchanged. The presentation of the Opening and Closing Ceremonies continue to increase in scope, scale, and expense with each successive celebration of the Games, but they are still steeped in tradition. The 2028 Los Angeles Olympics organisers propose that the opening and closing ceremonies will each, for the first time, be staged across two stadiums.
