The Nazca lines are a group of geoglyphs made in the soil of the Nazca Desert in southern Peru. They were created in two major phases – the Paracas phase (from 400 BC to 200 BC) and the Nazca phase (from 200 BC to 500 AD). The combined length of all the lines is more than 1,300 km (800 mi), and the group covers an area of about 50 km2 (19 sq mi). Most lines run straight across the landscape, but there are also figurative designs of animals and plants. Scholars differ in interpreting the purpose of the designs, but in general, they ascribe religious significance to them. The lines were designated as a UNESCO World Heritage Site in 1994. This is an aerial view of the geoglyph known as the "monkey", one of the most well-known in the Nazca lines.
