Gyeyangsan Mountain, which reaches an altitude of 395 meters, is considered a guardian and holy mountain that is representative of Incheon. The mountain’s name changed several times, according to the name changes of the region. It was previously called "Sujuak" as part of the Suju administration of the Goryeo dynasty, "Annamsan Mountain" during Annam administration, and finally was renamed "Gyeyangsan Mountain" during Gyeyang administration.

Gyeyangsan’s name originates from the area that is home to the Korean box tree, which produces cassia bark used to make cinnamon. Gyeyang Park was designated as Incheon’s first urban natural park on January 8, 1944, and since then, the mountain has gone on to become the city’s top municipal park.
