Gochangeupseong Walled Town was built in 1453 during th reign of Joseon King Danjong to protect the city from foreign invaders. The walls were built by the local civilians, using natural resources as they were available. Also called Moyangseong Fortress, the walled town served a vital role in protecting the southern region, and was designated Historic Site No. 145 on April 1, 1965. The walls are 4~6 meters high and 1,684 meters long, with three gates on the north, east, and west walls, each protected by curved walls. Inside the large area there were 22 government buildings. Restoration work on the wall has been ongoing since 1976.
