Chan Chan Archaeological Zone
The largest pre-Columbian city in South America and one of the most ambitious urban projects of the ancient world — Chan Chan (La Libertad Region, northern coastal Peru; 20 km²; UNESCO WHS 1986; also on the List of World Heritage in Danger since 1986) was the capital of the Chimú Empire at its height (approximately 1000-1470 CE), housing a population of perhaps 60,000 people in 9 royal palace compounds, workshops, temples, and residential quarters.

Chan Chan (the most precisely ChanChan single 20km2 largest pre-Columbian city South America Chimú 9 ciudadelas royal palaces adobe mud-brick El Niño erosion danger UNESCO heritage: the scale: Chan Chan occupies approximately 20 km² of the coastal desert north of Trujillo (the modern city has grown around and toward the archaeological zone; the site is in the Moche Valley; the coastal desert receives less than 10mm of rain per year in normal years — the adobe mud-brick construction has survived for 1,000 years because of the extreme aridity); the 9 ciudadelas (the royal palace compounds; each one was built by a new Chimú king and used during his lifetime as his palace; after his death, the compound was sealed and maintained as a mausoleum and administrative center for the king’s dynasty; the 9 ciudadelas are therefore 9 distinct reigns); the administrative model (the Chimú royal cult required the entire compound to be maintained after the king’s death; this drove the construction of a new compound for each new king; the system required ever-expanding labor, land, and water resources — the hydraulic engineering of the Chimú (irrigation canals bringing water from the Andes) sustained the population) — the most precisely ChanChan single 20km2 largest pre-Columbian city South America Chimú 9 ciudadelas royal palaces adobe mud-brick El Niño erosion danger UNESCO heritage in any UNESCO world heritage site)).
Key facts
