Photos: All the Celebrity Olympic Torch Bearers Over the Years

The Olympic Flame is a symbol of continuity between the ancient and modern games. It has been lit in a ceremony in Olympia, Greece, ahead of every Games since Berlin 1936, when the Olympic Torch Relay first began, according to Olympic.org. The relay, inspired by the torch races of Ancient Greece, begins when the flame is transported to the host country.

One year after arriving in Tokyo, the 121-day relay kicked off on March 25 in Japan's Fukushima prefecture, one of the areas hardest hit by the disastrous 2011 earthquake, tsunami and nuclear meltdown, according to The Washington Post.
