Mortarless Earthquake Proof Walls of Sacsayhuaman Might be Solved within 20 years


In the end, the most concrete indications of the abilities and practices of these earlier civilizations are found in the construction projects that impress stonecutters and archaeologists to this day. The zigzag wall of Sachsayhuaman stands as a stunning example of their ability to smoothly cut extremely hard andesite and granite stones, shape them with near perfection, and create structures that can withstand strong earthquakes and other natural disasters. While the Inca attempted to replicate the skills, the newer constructions it in and around Cusco clearly indicate they did not have what it took. Their buildings used mortar and fieldstone in many cases.



The archaeological site of Sachsayhuaman continues to provide intriguing glimpses into the far past. Stories come from locals and visitors alike of experiences and visions they saw at the location before changes were made or passages were blocked. For example, a modern Cusco resident who owns a restaurant used to work for the Ministry of Culture in Peru. He says that he and others walked down a large carved staircase to the east of Chinkana around 1992 before the way was blocked officially. He reports a very long series of tunnels and caves that were easily accessible for all men walking upright. Today, the Catholic Church who maintains ownership of Corhicancha block access due to its general lack of safety and complexity. They do not want people wandering in and getting lost in the sub tunnels and dark passageways. However, it obviously exists and may hold additional archaeological interest that could someday come to light.



Scattered around the whole area at the north side of Cusco light multiple archaeological digs sites and indications of ancient architecture and cultural artefacts. To the trained eye and the tour guides willing to share their knowledge with visitors, it becomes clear that the prominent Inca civilization not only built their world on top of or around whatever older groups created but actually incorporated them into the most important parts of their city. Undoubtedly, they appreciated the impressive stonework and architectural designs as much as we do today.
