Chan Chan is located in the mouth of the Moche Valley and was the capital of the historical empire of the Chimor from 900 to 1470, when they were defeated and incorporated into the Inca Empire. Chimor, a conquest state, developed from the Chimú culture which established itself along the Peruvian coast around 1400 AD. In the Chimú tongue, Quingnam, Chan Chan means "Sun Sun;" it was named for its sunny climate which is cooled year round by a southerly breeze.
Chan Chan is in a particularly arid section of the coastal desert of northern Peru. Due to the lack of rain in this area, the major source of nonsalted water for Chan Chan is in the form of rivers carrying surface runoff from the Andes. This runoff allows for control of land and water through irrigation systems.
The city of Chan Chan spanned 20 km² and had a dense urban center of 6 km² which contained extravagant ciudadelas. Ciudadelas were large architectural masterpieces which housed plazas, storerooms, and burial platforms for the royals. The splendor of these ciudadelas suggests their association with the royal class. Housing for the lower classes of Chan Chan's hierarchical society are known as small, irregular agglutinated rooms (SIARs). Because the lower classes were often artisans whose role in the empire was to produce crafts, many of these SIARs were used as workshops.
The coordinates chosen at right for the location of Chan Chan were determined using "Figure 1: Archaeological Zone of Chan Chan" from Michael West's article, "Community Settlement Patterns at Chan Chan, Peru". In this figure, it can be seen that Verlarde, Laberinto, and Bandelier form the northern border of Chan Chan while Uhle, Chaiguac, Tschudi, and Rivero form its southern flanks. The location chosen for the coordinates is in the center of these cities and so represents a central location for the ruins of Chan Chan amidst this archaeological zone.
The name is probably derived from the Quingnam "Jiang" or "Chang" which means Sun, from which Chan-Chan would be literally: Sun-Sun. It is hypothesized that its true meaning would be: Great sun, resplendent Sun, splendid sun or refulgent sun (since a typical feature of the Quingnam language is that the reduplication of a word acquires a new meaning). Another theory says that the name would derive from the term: Shian or Sian. The "Shi" voice translates as Moon and "An" as a house, meaning House of the Moon, making known that the Moon was the main deity.
After the Inca conquered the Chimú around 1470 AD, Chan Chan fell into decline. In 1535 AD, Francisco Pizarro founded the Spanish city of Trujillo which pushed Chan Chan further into the shadows. While no longer a teeming capital city, Chan Chan was still well known for its great riches and was consequently looted by the Spaniards. An indication of the great Chimú wealth is seen in a sixteenth-century list of items looted from a burial tomb in Chan Chan; a treasure equivalent to 80,000 pesos of gold was recovered (nearly $5,000,000 US dollars in gold).
In 1969, Michael Moseley and Carol J. Mackey began excavations of Chan Chan; today these excavations continue under the Peruvian Instituto Nacional de Cultura.
In 1998, The "Master Plan for Conservation and Management of the Chan Chan Archeological Complex" was drawn up by the Freedom National Culture Institute of Peru with contributions from the World Heritage Foundation – WHR, ICCROM, and GCI. The plan was approved by the Peruvian Government. Methods of conservation include reinforcement and stabilization of structures of main buildings and around the Tschudi Palace, using a blend of traditional and modern engineering techniques. Chan Chan currently has 46 points of critical damage, though the site's total damage far exceeds these points. The regional government of La Libertad is funding conservation efforts at these points.
UNESCO World Heritage Site
On 28 November 1986, UNESCO designated Chan Chan as a World Heritage Site  as well as placed it on the List of World Heritage in Danger. The World Heritage Committee's initial recommendations included taking the appropriate measures for conservation, restoration, and management; halting any excavation that did not have accompanying conservation measures; and mitigation of plundering. A Pan-American Course on the Conservation and Management of Earthen Architectural and Archaeological Heritage was funded by many institutes coming together, including ICCROM, the Getty Conservation Institute, and the Government of Peru.
The walled compounds (palaces) that make up the metropolis are the following:

|Chayhuac||Chayhuac An or Quixmic An||Chayhuac House or Beginning House|
|Uhle||Xllangchic An||East House or Sunrise House|
|Laberinto||Fechech An||West House or Sunset House|
|Gran Chimú||Utzh An||Big House|
|Squier||Fochic An||North House|
|Velarde||Ñing An||Sea House|
|Bandelier||Ñain An||Birds House|
|Tschudi||Nik An||Center House|
|Rivero||Chol An||New House or Final House|
|Tello||Tsuts An||Small House|
Walled compound Nik An (Ex Tschudi)
The walled complex "Nik An" is the greatest in illustration of the importance of water, particularly of the sea, and of the cult that surrounded it in the Chimu culture. The high reliefs of the walls represent fish, directed towards the north and the south (what can be interpreted as representation of the two currents that mark the Peruvian coast: that of Humboldt, cold, that comes from the south and the one of El Niño, hot, that comes from the north), waves, rombito (fishing nets), as well as pelicans and anzumitos (mixture of sea lion and otter).
This coastal society was governed by the powerful Chimucapac and was united by the force of a social control originated in the necessity of a strict management of the water, as well as by the external threats. The "Nik An" complex had a single entrance and high walls up to twelve meters for a better defense, and was wider at its bases (five meters) than at its summits (one meter), in anticipation of possible earthquakes on the seismic coast.
The city has ten walled ciudadelas which housed ceremonial rooms, burial chambers, temples, reservoirs and residences for the Chimú kings. In addition to the ciudadelas, other compounds present in Chan Chan include courts, or audencias, small, irregular agglutinated rooms (SIARs) and mounds called huacas. Evidence for the significance of these structures is seen in many funerary ceramics recovered from Chan Chan. Many images seemingly depict structures very similar to audencias which indicates the cultural importance of architecture to the Chimú people of Chan Chan. Additionally, the construction of these massive architectural feats indicates that there was a large labor force available at Chan Chan. This further supports evidence for a hierarchical structure of society in Chan Chan as it was likely that the construction of this architecture was done by the working class.
Chan Chan is triangular, surrounded by 50–60-foot (15–18 m) walls. There are no enclosures opening north because the north-facing walls have the greatest sun exposure, serving to block wind and absorb sunlight where fog is frequent. The tallest walls shelter against south-westerly winds from the coast. The walls are adobe brick covered with a smooth surface into which intricate designs are carved. The two styles of carving design include a realistic representation of subjects such as birds, fish, and small mammals, as well as a more graphic, stylized representation of the same subjects. The carvings at Chan Chan depict crabs, turtles, and nets for catching sea creatures (such as Spondylus. Chan Chan, unlike most coastal ruins in Peru, is very close to the Pacific Ocean.
Originally the city relied on wells that were around 15 meters deep. To increase the farmland surrounding the city, a vast network of canals diverting water from the Moche river were created. Once these canals were in place, the city had the potential to grow substantially. Many canals to the north were destroyed by a catastrophic flood around 1100 CE, which was the key motivation for the Chimú to refocus their economy to one rooted in foreign resources rather than in subsistence farming.
The ancient structures of Chan Chan are threatened by erosion due to changes in weather patterns — heavy rains, flooding, and strong winds. In particular, the city is severely threatened by storms from El Niño, which causes increased precipitation and flooding on the Peruvian coast. Chan Chan is the largest mud city in the world, and its fragile material is cause for concern. The heavy rains of El Niño damages the base of Chan Chan's structures. Increased rain also leads to increased humidity, and as humidity gathers in the bases of these structures, salt contamination and vegetation growth can occur, which further damage the integrity of Chan Chan's foundations. Global warming, if occurs as predicted by some, will only further these negative impacts, as some models suggest climate change facilitates increased precipitation.
