Excavations west of the monumental core at Chavín de Huántar, Peru in 2005 revealed a well-preserved plastered structure with a central circular hearth, in the style of the Mito Architectural Tradition. This find challenges standard definitions of both the Mito Tradition and Chavín itself. I discuss the material remains and associated radiocarbon dates from this feature, and use these new data to re-assess Chavín’s involvement in interregional networks and its relationship to earlier ceremonial centers in the Central Andean highlands.
