Until recently, an entrenched view of Tiwanaku expansion in the south-central Andes as a primarily cultic phenomenon precluded discussion of state-built ceremonial facilities outside of Tiwanaku’s immediate hinterland of the Bolivian altiplano. However, recent research in the Tiwanaku periphery has found specialized ceremonial architecture that reflects the solidification of central control and the development of a provincial system. Excavation at the Omo M10 site, in Moquegua, Peru, has exposed the only Tiwanaku sunken-court temple structure and cut-stone architecture known outside of the Titicaca Basin. A reconstruction of the Omo temple complex demonstrates direct parallels with Tiwanaku ceremonial centers of the altiplano in architectural form and ceremonial activities. This suggests that patterns of state-centered ceremony and peripheral administration underwent a dramatic transformation with the explosive expansion of the Tiwanaku state during the period known as Tiwanaku V (A. D. 725–1000).
