Sacsahuaman Wall

The Sacsahuaman Wall, located in Peru, is a wonder that ponders archeologists on how such a wall could have been built in the 17th century.

Pachacuti, who was an Inca ruler, overlooked 20,000 workers who started the original construction of Sacsahuaman in 1423. Located on a hilltop called Sacsachuman north of Cuzco, the walls are 1/3 of a mile and zigzag like sharp teeth. This project was completed 60 years later.

The Incas and its rulers would retreat into the Sacsachuaman when the city's defenses were broken down. It is unknown how the Incas were able to haul the huge blocks of stone to the hilltop by hand. With only the use of stone and bronze tools, the Incas were able to shape the stones so perfectly that it fit together like a jigsaw puzzle. Even the stones 60 feet up fit snuggly together, so that even today, a knife blade cannot fit between the stones. In fact the Sacsahuaman is so strong that it has survived earthquakes!!!
