The temple complex was constructed from 1406 to 1420 during the reign of the Yongle Emperor, who was also responsible for the construction of the Forbidden City in Beijing. The complex was extended and renamed Temple of Heaven during the reign of the Jiajing Emperor in the 16th century. The Temple of Heaven was renovated in the 18th century under the Qianlong Emperor.
In 1914, Yuan Shih-kai, then President of the Republic of China, performed a Ming prayer ceremony at the temple, as part of an effort to have himself declared Emperor of China.
The Temple grounds covers 2.73 km² of parkland, and comprises three main groups of constructions, all built according to strict philosophical requirements:
- The Hall of Prayer for Good Harvests is a magnificent triple-gabled circular building, 32 metres in diameter and 38 metres tall, built on three levels of marble stone base, where the Emperor prayed for good harvests. The building is completely wooden, with no nails. It had to be rebuilt after it burned down in 1889.
- The Imperial Vault of Heaven is a single-gabled circular building, built on a single level of marble stone base. It is located south of the Hall of Prayer for Good Harvests and resembles it, but is smaller. It is surrounded by a smooth circular wall, the Echo Wall, that can transmit sounds over large distances. The Imperial Vault is connected to the Hall of Prayer by the Vermilion Steps Bridge, a 360 meter long raised walkway that slowly ascends from the Vault to the Hall of Prayer.
- The Circular Mound Altar is the altar proper, located south of the Imperial Vault of Heaven. It is an empty circular platform on three levels of marble stones, where the Emperor prayed for favorable weather. It was built in 1530 by the Jiajing Emperor and rebuilt in 1740.
