Llamas were the preferred sacrificial animals of the Inka Empire, their ritual value second only to that of human beings. Recent archaeological excavations at the Inka settlement of Tambo Viejo in the Acari Valley on the Peruvian south coast have revealed a number of ritually sacrificed llamas in a unique context. This new evidence demonstrates that the establishment of Tambo Viejo as a provincial Inka centre involved the performance of ritual practices that included the dedicatory sacrifice of domesticated animals. These rituals materialised Inka imperial ideology and ultimately enabled the legitimisation of Inka presence in a conquered location.

We recently conducted excavations at the Inka administrative center of Tambo Viejo in the Acari Valley of the Peruvian south coast. Our excavation of two centrally located structures demonstrates that, despite the apparent brief occupation of the site, there was substantial rebuilding as older structures were demolished and replaced by new ones. The final layout of Tambo Viejo had been preceded by continuous modifications. Furthermore, the establishment of Tambo Viejo was accompanied by ritual activities comprising the burial of sacrificial offerings such as plants and animals.
