More than a hundred new designs discovered in and around the ancient Nazca Plains and surrounding areas in Peru could unearth new information about the mysterious pre-Columbian artworks that have fascinated scientists and visitors for decades.
After two years of field studies using aerial photography and drones, Peruvian and Japanese researchers from Yamagata University reported earlier this month the discovery of 168 new designs at the UNESCO World Heritage site on Peru’s southern Pacific coast.
The geoglyphs, giant figures carved into the South American desert, are more than 2,000 years old and depict humans, cats, snakes, killer whales, birds and native Camalids – animals like llamas, guanacos and alpacas.

Jorge Olano, chief archaeologist for the Nazca Lines research program, said the new figures averaged between two and six meters (6.56 to 19.7 ft) in length. The purpose of the Nazca Lines, which could only be seen from the air, remains a mystery.
However, this month’s results are smaller and can be seen from the ground, Masato Sakai, a Yamagata University professor who led the study, told Portal.
The figures, iconic remnants of Peru’s rich history, are about a three-hour drive from the capital, Lima.
Researchers had discovered 190 figures in the area since 2004. But the vastness of the terrain they cover has complicated heritage exploration and preservation efforts.

Yamagata University said the research will be used in artificial intelligence-based surveys to inform lineage conservation.
University studies in collaboration with the Peruvian government have helped delineate and protect the area threatened by urban and economic developments.
“Some geoglyphs are in danger of being destroyed due to the recent expansion of mining-related workshops in the archaeological park,” Sakai said.
