Founded in the first half of the 15th century, the Temple of Heaven is still surrounded by historic pine woods, in the Chongwen District of Beijing. The imperial complex of religious buildings was built for ceremonies of prayer by emperors of the Ming and Qing dynasties. The majestic complex includes the Altar of Prayer for Good Harvests, the Imperial Vault of Heaven and the Circular Mound Altar. The layout of the temple symbolises the relationship between earth and heaven which is at the heart of Chinese Cosmogony. In 1998, it was recognised by UNESCO as a World Heritage Site.
