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.
