Late Additions in the Eastern Plaza
At some point the inhabitants of Cuzcotuyo added two small rectangular rooms to the southern portion of the Eastern Plaza, as part of a broader renovation episode. To assess the function of these rooms, we set up one test unit in one of them (Room-4) (Figure 7.1). The excavations also exposed three occupational levels. The pre-Inka occupation over the sterile matrix was rather informal and was characterized by few utilitarian sherds (n=3). The next period in the Early Inka phase was marked by the resurfacing of the floor with a brown clay layer, including the construction of the stone foundations. No associated remains were uncovered. Therefore, this Early Inka occupation witnessed the erection of the main Cuzcotuyo complex and the onset of architectural investment. In the Late Inka occupation, a thick yellow clay layer was deposited covering the earlier occupation, as part of the entire architectural restoration.
Altogether, and as explained earlier in the chapter, three main occupational periods were identified in the main building complex. The pre-Inka occupation took the form of a discrete distribution of artifacts underneath selected rooms, associated with the local Manchachi Slate on Red pottery. In the following Early Inka period, the building complex was erected, and both plazas became the focus of public celebrations. In the last phase during the Late Inka period, the whole complex was reconstructed in order to enhance its defensive features, and one of the plazas was abandoned. This shift correlated with a change in the ceramic assemblage, considering the inclusion of Guarani-related pottery in the public celebrations.
