The Nazca Lines (or Nasca geoglyphs) are a vast collection of large- scale designs etched into the desert floor of southern Peru\u2019s Nazca Desert (Pampa Colorada and Pampa de Jumana), northwest of the modern city of Nazca. <\/strong><\/p>\n\n\n\n

They include hundreds of straight lines (some running for many kilometers), geometric shapes (trapezoids, triangles, spirals, rectangles), and figurative designs of animals, plants, and human-like forms. <\/p>\n\n\n\n

The figures range from tens to hundreds of meters long (e.g., a hummingbird ~50 m \/ 165 ft, a spider ~46 m \/ 150 ft, a monkey ~110 m \/ 360 ft, larger birds up to ~285- 370 m). The combined length of the lines exceeds 1,300 km, covering roughly 50- 500 km\u00b2 depending on how the area is defined.<\/p>\n\n\n\n

They were created mainly between about 500 BCE and 500- 600 CE (with the bulk associated with the Nazca period roughly 200 BCE- 600\/700 CE). Some earlier examples are attributed to preceding cultures.<\/p>\n\n\n\n

The Civilizations Behind Them<\/strong><\/h3>\n\n\n\n

The primary creators were the Nazca (or Nasca) culture<\/strong>, which flourished on Peru\u2019s southern coast between roughly 200 BCE and 600 CE in the river valleys of the R\u00edo Grande de Nasca drainage and the Ica Valley. <\/p>\n\n\n\n

They were skilled agriculturalists in an extremely arid environment, relying on sophisticated underground aqueduct systems known as puquios<\/em> to access and distribute water from Andean sources and aquifers. Their major ceremonial center was Cahuachi <\/strong>(a complex of adobe mounds and plazas), with Ventilla as a notable urban site. They produced distinctive polychrome pottery and fine textiles, and lacked a writing system.<\/p>\n\n\n\n
