An Amazing Virtual Tour Of The Old Summer Palace (Beijing)!

Delighted to have found this brief documentary (presented in the form of a virtual tour) highlighting the former glory of the old Summer Palace! My favourite section was the Zodiac Fountain, which featured 12 bronze Chinese zodiac statues. What's amazing about these statues is that they act as a water clock fountain by spouting water every 2 hours! I must admit I had no idea such technology even existed back in the 18th century :p Which section of this amazing wonder is your personal favourite?
