SUBSCRIBE NOW TO SPACE & PLANET: null There is real material evidence of ancient and mysterious abandoned ruins of civilisations lost to history in the Sahara desert. The specific ruins, which are the subject of this video are located in northeastern Niger on the Djado Plateau and the area is actually famous, not for these enigmatic ruins, but for it truly ancient cave art that depicts large animals that are no longer living in the region. The cave art is around 4,500 to 5,500 years old and the Djado ruins are believed to be around 1,000 years old. Studies of the Sahara Desert's climatic and geographical history show huge changes in conditions. The Djado Plateau was once a forest before transforming into lush grassland, perfect for raising livestock, herding sheep and goats and building settlements. Djado ending up as an oasis in the middle of the barren Sahara desert, as conditions became progressively uninhabitable. Watch the video to learn more about this largely unknown, unexcavated lost city in the Sahara, as well as the fortresses that were found in recent years in the Sahara desert of Libya.
