The Great Wall

     

In 221 BC Qin Shi Huang consolidated all the northern states and created the Qin Dynasty. Emperor Qin ordered the building of walls to connect the existing walls. This would become the Great Wall of China. This photo shows the Great Wall of China on a mountain ridge - can you find the three differences in this photo hunt puzzle?

Emperor Qin delegated a massive amount of manpower and resources to the effort. The builders discovered the most efficient way to build the Great Wall of China was by using resources from the surrounding areas.
