The Nazca Lines are a series of large ancient geoglyphs located in the Nazca Desert of southern Peru. Created by the Nazca culture between 500 BCE and 500 CE, these massive designs include various shapes, such as animals, plants, and geometric figures, some stretching over 1,200 feet in length. These mysterious lines were made by removing the top layer of reddish-brown iron oxide-coated pebbles to reveal the lighter-colored earth beneath. The purpose of the Nazca Lines remains a topic of debate among researchers, with theories ranging from astronomical calendars to religious rituals.
