Much of Jung-gu once lay within the old confines of Daegu Castle , which at one time comprised the entire town of Daegu . A small part of the castle wall is preserved in Dalseong Park . Many historical incidents in the history of Daegu took place in the district , including the recent Daegu subway fire and the February 28th movement calling for the end of the autocratic Rhee regime in 1960 . The district was formally established in 1963 , with the introduction of the '' gu '' system
