This thesis presents the results of archaeological excavations at the ancient human settlement of Cerro San Isidro in the Moro region of the middle Nepeña Valley, Peru. Domestic continuity is explored on the East Terrace over the longue durée to expand knowledge regarding household archaeology in the Nepeña Valley. Focusing on the Unidad de Excavación 5 (UE5) at the East Terrace (excavated in 2022), the study analyzes stratigraphic, architectural, and material data. Fieldwork conducted since 2019 by the Proyecto de Investigación Arqueológica Cerro San Isidro (PIACSI) reveals a rich and complex human occupation spanning over 2,500 years. Through block excavations covering 125 square meters, UE5 exposed stratigraphic contexts with multiple superimposed occupational and architectural phases. The recovered contextual information, including architectural organization, hearths, storage areas, food remains, and other material artifacts, suggests a series of multi-functional residential occupations on the East Terrace. Radiocarbon dating indicates intermittent occupation between 350 cal BCE and 1450 cal CE with a ceramic analysis confirming occupation during the Early Horizon, Early Intermediate Period, and reoccupation during the Late Intermediate Period. Adopting a diachronic lens of household archaeology and materiality over the longue durée, the thesis contextualizes the excavations within previous archaeological work in the region, describes field procedures and stratigraphic contexts, and provides a density analysis of features and material remains. The study integrates various strands of evidence to discuss the ancient occupation of the East Terrace and its implications for understanding the prehistory of the Moro region, Nepeña Valley, and the broader Central Andes.
