Nazca Lines: These ancient geoglyphs in the Peruvian desert are one of the world's most fascinating and mysterious places.

Up on high: The best way to see the Nazca Lines is from a small plane that flies over the desert.

The symbols: Many of the shapes have nicknames based on what they resemble -- this one is known as The Astronaut.

Watch out: The biggest threats to the Lines aren't from weather; they're from human beings. In 2018, a truck driver accidentally damaged some of the Lines.

World of wonder: The site was added to the UNESCO World Heritage list in 1994.

Behind the shapes: Many theories have developed about the Lines' origin and meaning, with some even believing they were made by aliens.

Working theory: However, most modern scholars believe the Lines were human-made and are connected to water sources.

The Condor: This bird shape is one of the best-known geoglyphs.

Maria Reiche: The small airport in Nazca is named for Reiche (pictured left), a German-Peruvian archaeologist known as the "Lady of the Lines."
