Pumapunku

Pumapunku or Puma Punku is a 6th-century T-shaped and strategically aligned man-made terraced platform mound with a sunken court and monumental structure on top. It is part of the Pumapunku complex, at the Tiwanaku Site near Tiwanacu, in western Bolivia. The Pumapunku complex is a collection of plazas and ramps centered on the Pumapunku platform mound. Today only the ruins of the monumental complex on top of the Puma Punku platform mound remain.

Construction of Puma Punku is believed to have begun after AD 536. Pumapunku was the most important construction in Tiwanaku, other than Akapana, which is believed to be "Pumapunku's twin". Among the place names in Tiwanaku, only the names "Akapana" and "Pumapunku" have historical relevance.
