Altar for Celestial God Worship Ritual(太白山 天祭壇)
Cheonjedan is the altar for celestial god worship rituals (cheonje).
It is generally located on the summit or at the foot of a mountain, and built without a roof structure, on the grounds bordered with a circle of rocks and the altar to one side. Mt. Taebaek Cheonjedan, on the mountain’s summit, is a large-scale ancient altar constructed of natural rocks. In Joseon (1391-1910) and under Japanese occupation in the first half of the 20th century, the altar was also called Taebaekcheonwangdang (Shrine for Celestial King), Taebaeksansa (Mountain Shrine), Taebaeksinsa (Shinto Shrine) and Taekbaeksa (Taebaek Shrine). The worship of Cheonsin (Celestial God) and the Taebaek Mountain God spread around the region, with many villages building similar altars on mountain peaks or below ridges to worship these deities. In these villages, Cheonsin is considered a deity of higher power than the village guardian deity Seonang and is worshipped as a higher god in rain rites (giuje) or in street rituals (georije). Cheonjedan serves as the venue for village rituals in Dongho-dong, Donghae, Gangwon Province. While most celestial god altars are built exclusively for Cheonsin, the Dongho-dong altar enshrines Tojisin (Earth God) and Yeoyeoksin (Plague Spirit) to the left and right of the celestial deity. A village ritual is held here each year on the first day of the first lunar month.
