Desc: Les secrets engloutis du titicaca: Directed by Frédéric Cordier. Never to date has a real archaeological excavation been undertaken in the mythical Lake Titicaca, in search of a possible pre-Columbian historical heritage that has been submerged for centuries or even millennia. This almost inland sea of 8400 km2 and located at an altitude of 3812 metres in the territory of Bolivia and Peru has always and tirelessly aroused the wildest imaginations and speculations among explorers, scientists and inhabitants of this remote region of South America. A delicate and exceptional expedition led by a young archaeologist from the Université Libre de Bruxelles and composed of some fifteen international scientists and archaeological divers set out to discover the mysteries surrounding the cold waters of this great lake of legends. And what they updated exceeded all expectations. Lake Titicaca is probably one of the most important and remarkable archaeological heritages on our planet.
