The Great Wall

     

The huge expansion of the Great Wall of China during the Ming Dynasty was mostly necessitated to keep out the Mongols to the north. The strongest wall fortifications were near the Ming capitol of Beijing. This photo shows a short segment of the Great Wall of China - can you find the three differences in this photo hunt puzzle?

In present times the most grandiose portions of the Great Wall of China (that tourists flock to) are near Beijing.

FYI - Use the arrows to advance next and back.
