Architectonical Complex of Cerro Mercachas: Architecture and Inca Rituality in Central Chile

Abstract

In this paper we discuss Inca occupation in the central zone of Chile, through the study of the biggest imperial site so far known in the area: the architectonical complex of Cerro Mercachas. An intra-site analysis was able to identify a linear and tripartite spatial organization of the site. Together with the scarce material culture identified, we suggest a ritual function for this site, related to festivities surrounding Inca metropolitan calendar or, at least, the observation of the December solstice and the Cerro Aconcagua cult. The overall archaeological context suggests a sporadic use of the site and by a limited number of individuals. This implies an exclusive ritualism for a selected few. Seen at a regional level, the high visibility of the site integrates this exclusive ritualism into the daily landscape of local populations, thereby reproducing the strategies of social construction of space that Tawantinsuyu executes in other areas. This new spatial order creates difference and hierarchy with local ritual spaces, thereby materializing a strategy of integration and exclusion between Tawantinsuyu and local populations. With these results we discuss the administration model traditionally used to understand Inca occupation in Central Chile.
