Eonyangeupseong Walled Town, Ulju

Eonyangeupseong is a rare example in Korea of a walled town built as a neat square on flat ground rather than on a hillside. It protected the old county of Eonyang, a crossroads on the routes linking Gyeongju, Ulsan, Miryang and Yangsan, and today its south gate Yeonghwaru, the curved outer wall and sections of rampart have been restored. Sitting right in the middle of Eonyang, it is easy to fit into a drive.

From earth to stone

Eonyang first had an earthen fortress. One record says it was built in 1390 at the end of Goryeo; another account traces earthen walls back to the Three Kingdoms period. In 1500, under King Yeonsangun, magistrate Yi Dam-ryong enlarged the fortress and rebuilt it in stone. It collapsed during the Japanese invasions of the 1590s, and the walls standing today are said to date from a rebuilding in 1617.

The walls follow the early Joseon method of stacking roughly dressed large stones and packing the gaps with smaller ones. That makes Eonyangeupseong valuable evidence of how walled towns were built in the 14th and 15th centuries, and of how fortification techniques changed between late Goryeo and early Joseon. It was designated a Historic Site in 1966.

What to see

• South gate Yeonghwaru: the restored gate pavilion, shielded by a semicircular ongseong wall so that attackers could not charge straight through the gate.
• The square circuit: each side measures about 380 m, for a total of about 1,520 m; some sources give a perimeter of about 1,000 m instead.
• Bastions and corner towers: all four gates had protective outer walls, with corner towers at the four angles and two bastions on each side, eight in total.
• Early Joseon masonry: compare the technique of filling gaps between large stones with small ones in the restored section by the south gate and in the surviving old stonework.

Good to know

• An eupseong protected the people of a county while serving military and administrative purposes. Unlike a mountain fortress, it enclosed the town where people actually lived.
• The official name changed from "Eonyangeupseong" to "Eonyangeupseong Walled Town, Ulju" in 2011.
• A geography of 1481 recorded Eonyangeupseong as an earthen fortress 1,489 cheok around and 8 cheok high, with two wells. When it was rebuilt in stone in 1500 it grew to 3,064 cheok around and 13 cheok high, with three wells.
• The Bangudae Petroglyphs, about 6 km away, were inscribed on the UNESCO World Heritage List in 2025 as the Petroglyphs along the Bangucheon Stream, so the two make a good Ulju history day.
• Eonyang is still a crossroads today: KTX Ulsan Station is a short drive away. For enquiries, contact the Ulju County tourism office (+82 52-204-0324).
