The largest Pre-Columbian city in South America, Chan Chan is an archaeological site located in the Peruvian region of La Libertad, five km east of Trujillo. Covering an area of approximately 20 km², Chan Chan was constructed by the Chimor (the kingdom of the Chimú), a late intermediate period civilization which grew out of the remnants of the Moche civilization. The vast mud city of Chan Chan was built between c.850 and c.1470 and was the imperial capital until Chimor was conquered by the Inca in the 15th century. It is estimated that 30,000 people lived in the city of Chan Chan
