No one knows exactly what Nazca lines are. The only indisputable fact is that they are located in South America, at the Nazca Desert plateau in the southern part of Peru.
Scattered around the plateau, the lines are gigantic geoglyphs representing geometrical and nature objects.
They are carved about 135 cm wide and 40-50 cm deep in the ground.
Made by the Paracas culture possibly as much as 1000 years before Nazca Lines, there are more than 1600 Palpa Lines and geoglyphs.
