The Sahara Geoglyphs are a unique phenomenon and an archaeological sensation of today. This grand phenomenon has yet to be reconsidered and studied in detail. But even now we can speak with confidence about another riddle of the past, of a scale no less than the mystery of the Nazca Plateau geoglyphs and many other similar mysteries. It can be said that the Sahara geoglyphs are the African Nazca desert, but considerably larger. There are no lines and drawings here, but there are tens of thousands of grand objects laid out of heavy boulders. They are located on a huge area and occupy almost the entire central part of the Sahara.
