A UNESCO World Heritage Site since 1994, the Nazca Lines are a series of ancient geoglyphs located in the Nazca Desert in southern Peru, in the high, arid plateau, about 400 km south of Lima. Scholars believe the Nazca Lines were created by the Nazca culture between 400 and 650 AD. The lines are best viewed from a plane, though they can be visible from surrounding mountains and was first documented in mid 16th century. The purpose of these lines are debatable. Archeologists, ethnologists, and anthropologists have studied the ancient Nazca culture to try to determine the purpose of the lines and figures. One hypothesis is that the Nazca people created them to be seen by their gods in the sky. Kosok and Reiche advanced a purpose related to astronomy and cosmology.

Each of the line can be as shallow as a few center meters deep and as narrow as 10 center meters wide. Some images are a close to be 200 meters in size.
