    local custom

What was asked for at this altar is not something the records say. What survives is who sacrificed here, when, and in what form. The state sacrifices of Goryeo and Joseon were performed here as a Daoist cho rite, and that tradition was revived in 1955 when the flame for the national sports festival was lit here; it continues as Gaecheondaeje, held each year on 3 October.

This site files the place under "miscellaneous" not for want of a better fit but because a rite offered to heaven cannot be transcribed into any of the ordinary categories of request.
