The Temple of Heaven is situated in the southern part of Beijing. It was first built in 1420 in the Ming Dynasty during the time when the Forbidden City ans some other important imperial structures were constructed. It covers an area of 273 hectares, which is 3 times larger than th Forbidden City. The Temple of Heaven is not only the largest group of temple building in China, but also the largest heaven-worshipping architecture in the world.
The Temple of Heaven was the place where the emperors of the Ming and Qing dynasties worshipped heaven and prayed for good harvests. The emperors visited the temple three times a year: on the 8th day of the first lunar month to pray for a good harvest; during the Summer Solstice to pray for rain; and during Winter Solstice to give thanks for a good harvest. During each ceremony, the emperors worshipped heaven and prayed for a good harvest. In addition, the emperors also worshipped their ancestors and other natural phenomena such as the Cloud God, Rain God and Wind God. In imperial days, the Chinese people believed that the sky was incircular shope and the earth was square. On the basis of this tranditional concept, the circle was widely adopted in the design of the temple's main building. It is in accord with people's imagination of 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 Circular Altar has three layered terraces with white marble. During the Ming and Qing Dynasties (1368 A.D. - 1911 A.D.), the emperors would offer sacrifice to Heaven on the day of the Winter Solstice every year. This ceremony was to thank Heaven and hope everything would be good in the future. The Hall of Prayer for Good Harvest is a big palace with round roof and three layers of eaves. Inside the Hall are 28 huge posts. The four posts along the inner circle represent four seasons-spring, summer, autumn and winter; the 12 posts along the middle circle represent the 12 months; and 12 posts along the outer circle represent 12 Shichen (Shichen is a means of counting time in ancient China. One Shichen in the past equaled two hours and a whole day was divided into 12 Shichens). The roof is covered with black, yellow and green colored glaze representing the heavens, the earth and everything on earth.
