Pumapunku (Puma Punka)
Puma Punku, truly startles the imagination. It seems to be the remains of a great wharf (for Lake Titicaca long ago lapped upon the shores of Tiahuanaco) and a massive, four-part, now collapsed building. One of the construction blocks from which the pier was fashioned weighs an estimated 440 tons (equal to nearly 600 full-size cars) and several other blocks laying about are between 100 and 150 tons. The quarry for these giant blocks was on the western shore of Titicaca, some ten miles away. There is no known technology in all the ancient world that could have transported stones of such massive weight and size. The Andean people of 500 AD, with their simple reed boats, could certainly not have moved them. Even today, with all the modern advances in engineering and mathematics, we could not fashion such a structure.
How were these monstrous stones moved and what was their purpose?
Puma Punku doesn’t look impressive: a hill as remains of an old pyramid and
a large number of megalithic block of stone on the ground, evidently smashed by a devastating earthquake. However, closer inspection shows that these stone blocks have been fabricated with a very advanced technology. Even more surprising
is the technical design of these blocks. All blocks fit together like interlocking building blocks.
