Just days before the opening of the XXXIst Olympic Games in Rio (5-21 August), this documentary uses the exploration of the ruins and new technologies to reveal the site of Olympia in Greece where the sporting contests were held in ancient times. Both a religious sanctuary and a sports site, Olympia was, for nearly one thousand years, host to the most prestigious games in Ancient Greece. Using reconstructions and 3D computer imagery, this documentary by Olivier Lemaître brings the past wonders of Olympia to life and immerses the viewer in the cradle of the Olympic Games.
