How a Ancient Building See Creative Thinking
I want to share a recent visit to Machu Picchu which is an Inca citadel located in the Eastern Cordillera of southern Peru. The citadel is built in 15th century for sacrifice and education but it was abandoned later due to unknown reasons.
The first amazing things to me is the whole citadel is built on the 2,430-meter mountain ridge. As our knowledge to build it looks simple today, but it was built about 600 years ago without any excavators and cranes. The ancient Inca people used the huge rocks on the mountain and chopped them into the structure they want. They also built bases at the edge of the citadel on each level to ensure the whole citadel not fall. Since Peru is on an active seismic zone, the ancient Inca people even knew how to build it with earthquake resistance. The second amazing thing to me is that the ancient Inca people built a creative drainage system which even works today. This creative drainage system is also built in the old capital for Inca empire, Cusco. Comparing with the poor drainage system I saw in Philadelphia and New York, I saw a wisdom behind this creative system.
