The Legend of Dangun and Chamseongdan
According to the Samguk Yusa (Memorabilia of the Three Kingdoms), Dangun Wanggeom, the son of the divine Hwanung and the bear-woman Ungnyeo, established the first Korean kingdom, Gojoseon. To offer sacrifices to the heavens, he is said to have built Chamseongdan on the highest peak of Ganghwa Island. The altar itself is a marvel of ancient philosophy: the round base represents the Heavens, while the square top represents the Earth.
For millennia, Korean kings from the Goryeo and Joseon dynasties traveled here to perform rituals during times of national crisis or celebration. Today, the sacred flame for the Korean National Sports Festival is still lit at this very spot every year, proving that the spirit of Dangun remains the heartbeat of modern Korea.
