The Mystery of Puma Punku’s Precise Stonework

Puma punku is the name of a large temple complex located near Tiwanaku, in Bolivia, and is part of a larger archaeological site known as Tiahuanacu. The temple’s origin is a mystery, but based on carbon dating of organic material found on site, archeologists believe the complex may have been built by the Tiwanaku empire - one of the most important civilization prior to the Inca Empire – that flourished between 300 and 1000 AD. The most intriguing thing about Puma punku is the stonework. Puma punku was a terraced earthen mound originally faced with megalithic blocks, each weighing several tens of tons. The red sandstone and andesite stones were cut in such a precise way that they fit perfectly into and lock with each other without using mortar. The technical finesse and precision displayed in these stone blocks is astounding. Not even a razor blade can slide between the rocks. Some of these blocks are finished to 'machine' quality and the holes drilled to perfection. This is supposed to have been achieved by a civilization that had no writing system and was ignorant of the existence of the wheel. Something doesn’t add up. Extraordinary craftsmanship is displayed in the stones. Photo credit An article from Wikipedia describes the fantastic engineering involved in the temple’s construction. In assembling the walls of Puma punku, each stone was finely cut to interlock with the surrounding stones and the blocks fit together like a puzzle, forming load-bearing joints without the use of mortar. One common engineering technique involves cutting the top of the lower stone at a certain angle, and placing another stone on top of it which was cut at the same angle. The precision with which these angles have been utilized to create flush joints is indicative of a highly sophisticated knowledge of stone-cutting and a thorough understanding of descriptive geometry. Many of the joints are so precise that not even a razor blade will fit between the stones.
