Chamseongdan Altar, Manisan, Ganghwa

An altar for heaven-worship rituals located on the summit of Manisan Mountain in Ganghwa-gun, Incheon, said to be the place where Dangun Wanggeom performed rites to heaven. The altar, made of stacked stones, sits atop the mountain and was regarded as a sacred space connecting to heaven. Even today, national events including Gaecheonjeol (National Foundation Day) and the lighting of the torch for the National Sports Festival are held here. It is a symbolic place that carries on the founding myth of the nation and the tradition of heaven-worship rituals.
