Funding from the Stahl Endowment of the Archaeological Research Facility at the University of California, Berkeley is making possible the essential work of managing the archaeological collections from the ancient Moche (ca. 200–850 CE) site of Pañamarca on the north coast of Peru. This work builds upon Stahl-funded activities in 2014 that allowed for the AMS dating of sixteen samples of organic materials recovered from architectural construction and botanical offerings excavated at Pañamarca. That new absolute chronology reveals that the site's famous painted temples were built and renovated in the seventh and eighth centuries CE and that religious activity continued at the site until at least the late twelfth century. The physical management and maintenance of the Pañamarca collections, their packaging, and shelving is essential to preservation of the site’s material culture, and will be a necessary step in the next phase of research.
