The Temple of Heaven was the place where the Emperors of the Ming and Qing dynasties would worship Heaven and pray for bumper crops. The northern part of the outer surrounding wall is semi-circular in shape while the southern part square, a pattern symbolic of the ancient belief that Heaven was round and the earth square. The double surrounding wall separates the temple into two parts—the inner and outer temples with the main structures in the inner one, covering a space of 273 hectares in all.
　　A masterpiece of the Ming and Qing architectural art and a precious example of China's ancient architecture, the Temple of Heaven is the largest architectural group for worshipping Heaven in the world.
