The temple complexes on the island of Philae were discovered by European explorers in the 18th century and are among the largest sites of ancient Egypt. Philae was declared a UNESCO World Heritage Site in 1979 and has been a popular destination for culturally interested visitors from all over the world ever since. In this documentary, the fascinating story of the sunken temple sanctuary from the time of Cleopatra's dynasty is told in detail for the first time.

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.
