Located in Bolivia, near Lake Titicaca, lay the ancient ruins of what is thought to have been a pyramid and temple known as Pumapunku. Believed to have been constructed around 400 to 600 AD, the Tiwanaku are credited with Pumapunku but left no written record as to how the site was created.
For archaeologists the extraordinary parts of Pumapunku are the megalithic stones used to construct it. Several of them weigh anywhere from 100 to 200 tons with the largest stone weighing in at over 400 tons.
These massive blocks of stone were quarried from a site located 10 miles from Pumapunku. Once quarried the stone blocks had to somehow be moved out and up a steep hill where they were then taken to the Pumapunku site which was located at the top of a mountain.
Since the Tiwanaku were not thought to possess the wheel, archaeologists are still baffled as to how these enormous blocks of stone were moved from the quarry to their final resting place at Pumapunku.
Another astonishing aspect for archaeologists who have studied the Pumapunku ruins is the Tiwanaku's advanced masonry abilities. Each block of stone is cut with such precision they appear to have once fit together like the pieces of a puzzle.
Some of the stones that remain together and intact are placed so precisely that it is said not even a razor blade could fit between them.
Interesting still are the megalithic stones that display impossibly straight, cut lines which contain tiny holes, each one spaced the exact same distance apart, and which appears to be the product of some extremely advanced drilling method.
Since the stone blocks are made of a very hard granite, tools made of stone, copper and bronze of the Tiwanaku time period are not thought to have been able to carve, cut or drill the granite stones with the exactness that Pumapunku displays.
Archaeologists agree that the technology and masonry applied by the Tiwanaku at Pumapunku was highly advanced and hundreds of years ahead of their successors, the Incas.
