The centre of Ulsan is generally regarded as Seongnam-dong, in central Jung District. Here lies Dongheon (동헌), an old complex used by the Japanese as a base of government during the occupation of Korea. Also in Jung District are Hyanggyo (향교), the old Confucian Academy, Byeongyeongseong (병영성), an old hill fortress of which very little remains today, and an ancient stupa atop the hill known as Hakseong Park (학성공원). This stupa is the only one in South Korea to have the Oriental Zodiac figures carved around its base. Ulsan Central Market, the largest traditional market in Ulsan is located in Jung District.
