About this place

The Cheonjedan stands on the summit of Taebaeksan in Taebaek, Gangwon, and was designated National Folklore Cultural Heritage in 1991. The Cheonwangdan at the peak has the Janggundan behind it to the north and a lower altar below the southern slope. The Cheonwangdan is an oval stone platform 2.4 metres high and 27.5 metres around. A rite is offered every 3 October, National Foundation Day.

Origin and history

The Encyclopedia of Korean Culture records that the altar was designated National Folklore Cultural Heritage in 1991. The Cheonwangdan at the summit has the Janggundan behind it to the north, and a lower altar below the slope to the south.

The Cheonwangdan is a great oval stone platform: 2.4 metres high, 27.5 metres in circumference, 7.36 metres across and 8.26 metres front to back.

Taebaeksan was early counted the northern peak among Silla’s three mountains and five peaks, held as a guardian mountain, and a record of state sacrifice there survives in the rites section of the Samguk Sagi.

    A record of state sacrifice here survives in the rites section of the Samguk Sagi.

    documented history

What this altar is for, the record does not say. What survives is who sacrificed, when, and in what form. A rite is performed every 3 October, National Foundation Day, and is called the heaven rite or the heaven-king rite.

This site files the place under "other" for the same reason it does Chamseongdan on Ganghwa: a rite offered to heaven cannot be rewritten into any of the existing petitions.

One thing more is worth recording. The encyclopedia notes that the Taebaeksan area is still regarded as a sacred mountain and as a training ground for becoming a shaman. It is a place where people become mudang and where they train — which is also to say that it is not a preserved ruin.
