Gigante de Tarapacá

In the Atacama desert there are more than 5000 geoglyphs which were constructed between 800-1500 AD by (among others) the Tiwanaku and Inca cultures, probably for symbolic and ritualistic purposes but most importantly to mark out safe passages through the desert.
The Atacama giant on the slopes of Cerro Unita is the largest human-like geoglyph in the world. It dates from pre Inca times, is 86m long and said to depict a shaman holding a medicine bag and arrow and wearing a jaguar mask. It is also thought to have served as an astronomical calendar.
