The Cult
No ancient cult of Hwanung is directly attested. The myth records him as the son of Hwanin who descends to earth to found a sacred city on Taebaeksan; this narrative later licensed mountain rituals rather than documented temples. The Chamseongdan altar on Taebaeksan, rebuilt in stone in later centuries, and the larger Chamseongdan on Manisan, Ganghwa Island, became sites where Korean kings offered sacrifice to Heaven. These rites are ancestral to Hwanung's story rather than proof of it: they show a long tradition of heavenly descent mythology that the Samguk Yusa later attached to his name.
