<u>Famous artworks called Nazca Lines exist in southern Peru.</u><u> They were made in the span between 500BC and 500 CE </u><u>by Nazca people</u><u> and they go up to 1km. These geoglyphs (large designs on the ground) still remain a mystery, as it is not sure what the purpose is and exactly how they were made.</u> Researchers suggest they were completed by groups of Nazca people. Either way, it is impressive how coordinated they are considering the culture did not have means of seeing the shapes from the air.
