Strange Ancient Discoveries For Which There Is No Explanation
Near the city of Cuzco, more than 3500 meters above sea level, these amazing walls first fascinated the Spanish conquistadores. They were astonished to discover how these people, according to them, were ignorant and lacked the ability of logical reasoning required to have built such wonders. They are in fact 3 concentric walls, the average being roughly 360 meters in length and 6 meters in height, made from limestone blocks that weigh about 300 tons each. They didn’t use mortar or any other kind of cement to bind the walls, but they are carved and placed in such a way packed so closely that even a sharp knife can’t be wedged between 2 blocks. Scientists have tried to achieve this at a much smaller scale and have failed in their efforts to replicate the tight joints of the Sacsayhuaman walls.
