Temple of Heaven: Where the Square and the Circle Met

· #北京#天坛#世界文化遗产#祭天#祈年殿

East of the Yongdingmen inner avenue in Dongcheng district there is a quiet patch screened by cypress. For the Ming and Qing dynasties the emperor came here every winter solstice to worship Heaven and every spring to pray for a good harvest; nobody else was allowed near. UNESCO inscribed it in 1998 as “a masterpiece of human art,” and added that its architecture and landscape planning “exercised a profound influence on building and planning in the Far East.”

The temple complex, circular at the north and square at the south.

Numbers and rules

First built in 1420, it covers some 273 hectares — a little over four thousand Chinese acres. Two walls enclose it, the outer one forming a squared outline with a closed central court, while the inner wall is round at the north and square at the south: the sky is round, the earth is square. Six structures matter: the Hall of Prayer for Good Harvests, the Circular Altar, the Hall of Heavenly Compassion, the Fasting Palace, the Bureau of Musical Rites and the slaughterhouse. In 1961 it was named a national heritage site, first batch.

From honouring heaven and earth together

In the Yongle years the complex was called the Altar of Heaven and Earth. The original Hall of Great Ritual was not round at all: eleven bays wide, rectangular, crowned with yellow glazed tiles, and used for sacrificing to heaven and earth in one service.

The turning point came under the Jiajing emperor. In 1530 he reinstated the older practice of worshipping the two separately — the earth altar was built out at the northern suburb, the existing altar was re-tasked with Heaven alone, and to the south of the great hall a new open-air three-tier circular stone altar appeared, the Circular Altar, for the winter solstice rite. In 1538 the great hall was rebuilt as a three-eave circular building and renamed the Hall of Grand Harvests, used for the spring prayer; its three roof tiers carried blue, yellow and green glaze in turn, representing heaven, earth and all things. That fixed the layout “prayer for grain at the north, altar at the south.”

The Qing inherited the whole rite. The single largest change came in 1751, during the Qianlong era: the hall was renamed the Hall of Prayer for Good Harvests and all three tiers were reglazed in blue, to make Heaven unmistakably supreme. Around the same time the Circular Altar’s platforms, balustrades and posts were recalibrated so that their dimensions and counts are all multiples of nine, and the platform stones were replaced with blue-grey marble quarried near Beijing. The Hall of Heavenly Compassion and the Fasting Palace were enlarged and repaired too.

The hall of prayer: an arithmetic of thirty-two columns

Three eaves, circular, roughly 32 metres across and 32.8 metres tall, carried on thirty-two nanmu columns — four giant central ones, twelve gold columns and twelve eave columns, which add up to twenty-eight and match the twenty-eight lunar mansions. Blue glazed tile from base to ridge, and nothing but blue above the sea of cypress. It is worth walking around once.

Inside the hall: nanmu columns and painted brackets.

The altar and the wall that carries sound

The Circular Altar to the south is an open three-tier stone terrace. The round slab at its centre is the taiji stone; stand on it and speak, and the balustrades bounce your voice back so strongly it seems amplified. North of it stands the single-eave round Hall of Heavenly Compassion, ringed by the famous Echo Wall — whisper from one side and the person on the other hears you clearly, because sound travels along the curved surface. Nobody left a formula for it.

One bridge and a piece of protocol

Heading north from the altar you cross the Royal Bridge: three metres high, some thirty wide, and a long stone causeway. Ming and Qing emperors fasted and bathed before the rite and walked this bridge in silence. The cypresses beside it are older than the buildings, and walking under them lowers your voice without asking. On the first and fifteenth of each month it opens to the public, and Beijingers turn up to sing, play chess and do tai chi. Sacred ground and public square share the same mornings here.
