The Nazca Lines are a series of geoglyphs located in the Nazca Desert, a high arid plateau that stretches more than 50 miles between the towns of Nazca and Palpa on the Pampas de Jumana in Peru. Believed to have been created by the Nazca culture between 200 BCE and 700 CE the lines are shallow designs in the ground where the reddish pebbles that cover the surrounding landscape have been removed, revealing the whitish earth underneath. Hundreds are simple lines or geometric shapes, and more than seventy are natural or human figures. The largest are over 200m across and they are spread over an area of nearly 190 square miles.
There are many theories about why the Nascar lines exist, mostly pointing towards a religious significance, the worship of the life giving mountains and other water sources, a message only the gods could see. The geometric lines could indicate the flow of water or be connected to rituals to summon water. Some lines seem to line up with celestial bodies at certain times of the year. The spiders, birds, and plants could be fertility symbols. Other possible explanations bandied about include: irrigation schemes, giant astronomical calendars, or parking spots for spaceships, widely accepted is the theory that the lines were used as sacred paths leading to places where these deities could be worshiped, and the figures symbolically represent animals and objects meant to invoke their aid. Maybe they just liked monkey´s. Hey, who doesn't?!
