The Temple of Heaven was built in 1420, the eighteenth year of the reign of Emperor Yongle of Ming Dynasty. It was where the emperor of Ming and Qing Dynasty worshipped the Heaven. The Temple of Heaven is divided into the inner and the outer parts. Danbiqiao (a raised grand open-air passage) links the Altar of Prayers for Bumper Harvests of Grain in the north and the Circular Mound in the south forming an axis-line.

All above are the treasure of the ancient buildings and the masterpiece of the ancient masters, being in a major position in the architectural history of China. The main buildings in the park include the Hall of Prayers for Good Harvests, the Imperial Vault of Heaven, the Circular Mound, the Hall of Abstinence, the Echo Wall and the Long Corridor.
