Templete Semisubterráneo Tiwanaku

East of the main entrance to Kalasasaya, a stairway leads down into the Templete Semisubterráneo, an acoustic, red-sandstone pit structure measuring 26m by 28m, with a rectangular sunken courtyard and walls adorned with 175 crudely carved stone faces. In the 1960s archaeologists tried to rebuild these and used cement between the stones.
