As far as scale models go, I'm not sure you'll ever find out quite as impressive as this absolutely enormous one depicting what Shanghai is supposed to look like in 2020. At over 1,000 square feet, it shows every single building in China's most populated city, or at least every single building planned.

It's on the third floor of the Shanghai Urban Planning Museum, and it is in fact the largest scale model of a city in the world. The attention to detail is absolutely astounding.
