Researchers at the University of Yamagata in Japan examined 100 of the geoglyphs and deduced that one group used the lines as part of their pilgrimage to Cahuachi, a major ceremonial centre.
The other group appears to have smashed pots at the lines’ intersection, perhaps using them for religious ceremonies.
The Nasca Lines have long been the subject of endless speculation about who made them, how they were made and what they were used for.
Now designated as a UNESCO World Heritage Site, the lines were first made famous in 1939 when a pilot spotted them while flying over the Peruvian coastal highlands.
The strange shapes in the desert include geoglyphs of animals, supernatural beings and geometric designs.
