If you are on your Beijing China tour and very interested in Chinese ancient historical buildings, Beijing Forbidden City and Beijing Great Wall certainly are the golden mark. However, when you are exploring Beijing Temple of Heaven, did you have a completely research? Have you got the specific content of this grand building? Today I would like to introduce you one surprised spot to entertain your Beijing travel.

The famous Circular Mound Altar was where the sacrificial rite was held on the winter solstice. As a three-tier round platform built with bluestone, this building was designed as a holy land. Each terrace is edged by white marble balusters. The number of both flagstones in a circle and baluster posts is multiple of nine, as nine represents infinity which is the feature of the heaven. Tours in Beijing, standing on the flagstone in the center and speak in a very quiet low voice, you would hear the echo in 0.07 seconds. Located the north of the Circular Mound is the Imperial Vault of Heaven where the famous tablet of God of Heaven is placed. The main hall is built to be a round pavilion with dark blue roof symbolizing heaven. Most interesting is that if you whisper into this hall, another person standing in the far distance would hear you clearly.
