This work presents an anthropological study of crania and mandibles from the osteological collection from Chinchero (Peru), currently housed at the American Archaeological and Ethnological Museum of the Complutense University of Madrid. From 1968 to 1971, a team of archaeologists of the Spanish Scientific Mission in Hispanic America excavated the site of Chinchero, a small village located in the Andean high plateau near Cusco. As the result of this mission, remains from 8 single burials and two ossuaries dated to pre-colonial times were exhumed and brought to Spain. The excavated area included an ancient palace and several administrative and religious structures built by Tupac Yupanqui, who ruled the Inca Empire between 1471 and 1493. The surroundings of the catholic church, erected over one of these buildings, were excavated as well.
