About
About Cahuachi (Ica – Nazca Province)
Capital and pilgrimage center of Nazca culture (400 BCE–500 CE) – 24 km² desert metropolis with 34+ pyramidal adobe mounds (Great Pyramid 22 m high, 100×150 m base; Orange Pyramid), plazas (Great Temple plaza 2 ha), terraced habitations and geoglyph-linked sightlines. Never residential-military but ceremonial aggregation of 6,000 occupants. Conical cane-adobe (quincha) wall construction with color washes. Excavated by Alberto Saxe, William Strong and since 1982 Giuseppe Orefici (CISRAP, 40+ seasons) revealing textile workshops, trophy heads and Pan-Andean drum ceramics; abandoned 500 CE after 200–450 CE El Niño mudslides from Huayuri valley. Mother settlement for Pampa Colorada Nazca Lines.
Why it mattersLargest Nazca site redefines Nazca from desert geoglyph-makers to urban-pilgrimage civilization; proof Cahuachi supplied Lines pilgrimage logic.
