|The Incas were a civilization in western South America near Cuzco, Peru. You may have heard of Machu Picchu, an ancient fortress city of the Incas in the Andes Mountains. The Incas were superb craftsmen and architect-engineers. Nazca Lines are geoglyphs (drawings on the ground) that are believed to have been created by The Incas during the 15th and 16th centuries. There are about 300 figures - among them are geometric shapes.
