The Temple of Heaven is a worthwhile visiting place in Beijing. It is much bigger than the Forbidden City and smaller than the Summer Palace with an area of about 2,700,000 square meters. The Temple was built in 1420 A.D. during the Ming Dynasty to offer sacrifice to Heaven. As Chinese emperors called themselves #The Son of Heaven# ,they dared not to build their own dwelling,#Forbidden City# bigger than a dwelling for Heaven.
The Temple is divided by two enclosed walls into inner part and outer part. The main buildings of the Temple lie at the south and north ends of the middle axis line of the inner part. The most magnificent buildings are The Circular Mound Altar (Yuanqiutan), Imperial Vault of Heaven (Huangqiongyu) and Hall of Prayer for Good Harvest (Qiniandian) from south to north. Also, there are some additional buildings like Three Echo Stones and Echo Wall.Almost all of the buildings are connected by a wide bridge called Vermilion Steps Bridge (Danbiqiao) or called Sacred Way.

The Vermilion Steps Bridge connects the Hall of Prayer for Good Harvest and the Imperial Vault of Heaven. The south end of the Bridge is lower than its north end. The emperors in the past believed that they could go to heaven through this Bridge, which is why this bridge is also called Sacred Way. A Yu Route and a Wang Route are on two sides of the Sacred Way. The former one is only for the emperors to walk on and the later one is for the princes and the high officials to pass.
Three Echo Stones is outside of the gate of the Imperial Vault of Heaven. If you speak facing the Vault while standing on the first stone, you will hear one echo; standing on the second and then the third stone, you will hear two and three echoes respectively.
