B: AN IMAGE OF A GREAT PIECE OF ARCHITECTURE

The Zhaozhou Bridge is a large stone-arched bridge located on the Xiaohe River in Hebei Province in China. It is China's and the world's oldest and best preserved big stone arch bridge, having a far-reaching impact on the bridge building of later ages. What deserves a special mention is the "open spandrel" structure of the bridge, which was unprecedented in the world's bridge building history. The earliest open spandrel arch bridges in Europe were built about 1100 years later than the Zhaozhou Bridge of China.
At the same time, the designer expressed his whishes for the stone bridge's power to permanently keep floods at bay, as you can see from the different size holes on the body. I think it great because the bridge is a perfect combination of ancient Chinese architectural art and superb techniques, reflecting the wisdom of Chinese ancient craftsmen.
