Geoglyphs are large designs or motifs created on the ground, often formed by arranging stones, earth, or other materials. These impressive artworks can be found in various parts of the world, with the most famous examples being the Nazca Lines in Peru. They are believed to have been created by ancient cultures for ceremonial purposes or as astronomical markers. The creation of geoglyphs requires significant planning and labor, as they can span hundreds of meters. Their visibility from the air has led to much speculation about their purpose, with theories ranging from religious significance to navigation aids. The preservation of these sites is crucial, as they provide valuable insights into the cultures that created them.
