About this place

Sancheondan, the altar for the Hallasan mountain-god rite, stands in Ara 1-dong, Jeju City, ringed by black pines. On Jeju the mountain-god rite had been held at the summit of Hallasan since Goryeo times, but when the weather turned during the rite in the second month the hardship on the islanders was severe, and there were cases of people freezing to death. In 1470 Yi Yak-dong, then governor of Jeju, had an altar built here so that the rite could be held at this place, to spare the islanders the ordeal; from then on the mountain-god rite was held here on the first jeong day of the second month. In earlier times the heaven rite was performed up at Baengnokdam, but when the way was hard and the weather cold an altar was made here and the rite performed at it, which is said to be how the place got its name. The black pine group was designated a natural monument on 31 January 1964.

Origin and history

On Jeju the mountain-god rite had been held at the summit of Hallasan since Goryeo times. But when the weather turned during the rite in the second month, the hardship on the islanders was severe, and there were cases of people freezing to death.

In 1470 Yi Yak-dong, then governor of Jeju, had an altar built at Sancheondan so that the mountain-god rite could be held there, in order to spare the islanders the ordeal. From then on the rite was held here on the first jeong day of the second month each year.

In earlier times the heaven rite was performed up at Baengnokdam; when the way was hard and the weather cold, an altar was made here and the rite performed at it, which is said to be how the name Sancheondan arose.

The black pines standing on and around 375-1 Ara-dong and five neighbouring lots were designated a natural monument on 31 January 1964.

    The black pines

    The pines standing around the altar were designated a natural monument on 31 January 1964.

    documented history

This altar stands here not for a reason of belief but because people died. The mountain-god rite belonged at the top of Hallasan, and when the second month’s weather turned savage those who had climbed froze. When Yi Yak-dong built an altar below the mountain in 1470 and moved the rite to it, he did so to spare the islanders the ordeal. Where the rite was held was settled by an official’s judgement, and what that judgement rested on was people dying of cold.

Places that stand in for somewhere unreachable are already on this site. Okitsugu Yohaisho in Fukuoka is a hall for bowing across the water toward an island no visitor may enter, and Yamaguchi Jinja and Soma Jinja in Sapporo were both raised to face somewhere too far to go. But those look toward the distant place. This one brought the rite itself down.

The name came out of the same circumstance. The heaven rite used to be carried up to Baengnokdam; when the way was hard and the cold severe, an altar was made here instead, and the place has been called Sancheondan since.

What keeps the ground now are the pines. The trees designated a natural monument on 31 January 1964 stand around the altar.
