The Olympic flame is set to be lit in Greece later today. The Ritual of the Lighting Ceremony will take place at the Temple of Hera in ancient Olympia just before ten o'clock.
It's where the High Priestess and Priestesses enter the Ancient Stadium to light the flame and hand it over to the first Torchbearer.
The Opening of the Torch Relay kicks off half an hour later. The torch will begin it's journey to London in a week for the 2012 Games.
