Abstract

Since 2002, the Italian Mission of CNR-ITABC has been operating in the archaeological complex of Chan Chan (Peru), which is the largest pre-Columbian settlement entirely built with adobe. In 1989 Chan Chan was placed on the UNESCO World Heritage List. The main purpose of the work is aimed at the conservation, documentation and use of the site and of the territory that is related to Chan Chan from a historical and cultural point of view. The urban structure of Chan Chan, which is spread over a surface of 14 km2, has a number of buildings which characterizes the town at both an architectural (ciudadelas, huacas, huachaques) and decorative level (bas-reliefs, geometrical motifs). In order to achieve our research goals, we had to arrange for the combined use of various analysis techniques that would provide both urban and architectural information about the town. The data we obtained allowed us to make a more up-to-date interpretation of the urban fabric and revealed intriguing details regarding the construction phases of one of its palaces which will be helpful both for the planning of the Archaeological Park and the restoration project of the Palacio Rivero.
