In 500 BCE, ancient people created vast animal and geometric figures in Peru's desert. 2,500 years later, the Nazca Lines remain one of archaeology's great enigmas

Nazca Lines archaeological mystery: Giant geoglyphs in Peru's arid plains have survived for over two millennia. These Nazca and Palpa Lines depict animals, plants, and geometric shapes. Created between 500 B.C. and A.D. 500, their purpose remains a mystery. The site's extreme dryness preserved these ancient artistic achievements.
