Introduction to the ancient city of Changchang: As the capital of the Chimu Kingdom, Changchang created a splendid civilization from the 9th to the 15th century. At the end of the 15th century, the Chimu Kingdom was captured by the Inca army, and Changchang became a ruin in the desert. In 1986, the Changchang archaeological site was included in the World Heritage List and the List of World Heritage in Danger by UNESCO.
