The politics of provincial site planning and the architectural evolution of the Inka administrative center of Turi, northern Chile

Abstract

Political aspects of imperial architecture are usually evaluated in terms of the symbolism of specific buildings as opposed to overall site planning and layout. This reflects a shortcoming in our understanding of imperial tactics, as provincial site layouts were likely politically calculated. Here we present an architectural study of the Inka provincial capital of Turi, a well-preserved local population center in northern Chile co-opted for Inka imperial administration of the Atacama Desert area. We reevaluate layout planning at the site using concepts of building coordination and inter-site standardization to identify potentially planned features, and add to this a chronological study of surface architecture based upon wall-abutments and radiocarbon dates associated with a sample of building events. Results indicate significant Inka-era remodeling took the pre-existing site’s layout in a more coordinated and monumental direction, serving to increase site symmetry, reference political ideas through inter-site standardization, and focus greater attention upon Inka political buildings. Political buildings themselves grew more formalized and monumental over the course of the imperial occupation, culminating in the construction of a large kallanka state building near the end of the 15th century. Overall, we argue that layout remodeling was used to form increasingly strong architectural pronouncements of state legitimacy over time, and that moving past a ‘planned’ versus ‘unplanned’ conceptual binary will aid in gleaning more information from imperial sites in future research.
