During its peak (724- 1172 AD) the Tiahuanacan Empire covered nearly all of Bolivia, Northern Chile and Southern Peru, ruling over more than three million subjects.The Akapana pyramid was once a seven-step pyramid measuring some 200 meters on each side and standing nearly 17 meters tall.
On the northeast and southeast corners of the Pumapunku, it has 20-metre (66-foot) wide projections that extend 27.6 metres (91 feet) north and south from the rectangular mound.In addition, the style, size and skill demonstrated by the vast number of precision-cut cyclopean stones at Tiahuanaco (and nearby Puma-punka) reminds us that cutting and moving 100 ton stones was common-place for the highly skilled builders of the complex, who also managed to move the stones over tens of miles from distant quarries to Tiahuanaco, which at such a high altitude is in itself, a remarkable physical feat.The city was the administrative and religious heart of a pre-Incan civilisation that began in the year 237 BC and endured for over 1400 years.The location is curious as a lake nearby to lake Titicaca, with which the site is associated, is a sea-water lake, apparently with sea-fauna still present.Indications of man-made structures below the level of lake Titicaca (which is slowly drying up over time), suggests that our understanding of the site is far from complete.The Pumapunku complex consists of an unwalled western court, a central unwalled esplanade, a terraced platform mound that is faced with stone, and a walled eastern court.
The Pumapunku is a terraced earthen mound that is faced with blocks.
A staircase with sculptures is present on its western side.
Possible residential complexes might have occupied both the northeast and southeast corners of this structure.
The remains of the site are now finally being restored.
Tiahuanaco sits high in the Andes at an altitude of around 2 miles above sea level.
This terrace is paved with multiple, enormous stone blocks.
