Puma Punku or "Gate of the Puma" is one of the temples in Tiwanaku with highest architectural achievements. It is built on approximately 2 hectares and has a piramide structure sitting on three platforms.
This building was done at the end of the classical period of Tiwanaku, since the tecniques used to build it are much more refined than for other structures, above all the use of limestone rocks is quite notorious here.
On the upper part of this construction you can find a small temple with drainage channels clearly defined. To the west you can see the remains of some type of stairway. The main yard is found on the north east with the remains of what were probably four rooms with gates similar to the gate of the sun.
The use of copper rings and other metals for the union of certain construction elements is quite notorious here, the ground surrounding the temple has a reddish color probably due to use of certain ceramics for its construction.
Unfortunelly this monument has been one of the most looted ones, before, during and after the colonial period, first by the Incas, then the Spanish and also during the republic.
