Pachacamac
The site of Pachacamac is found on the Peruvian coast just south of Lima. For nearly a millenium this site was considered sacred by the ancient peoples of the Andes. It was believed to house a powerful oracle, and was in use through the time of the Spanish Conquest. Different pan-Andean cultures built monumental structures on the grounds of Pachacamac, and it served as a large pilgrimage center.
For my dissertation I examined skulls from Pachacamac, curated at the National Museum of Natural History of the Smithsonian Institution. With such a sizeable collection issues such as ethnicity and class can be explored in depth.
