Seosaengpo Japanese Fortress

서생포왜성

A war-era hill fortress with sea views

Address

Seosaeng-ri, Seosaeng-myeon, Ulju-gun, Ulsan

Japanese forces built this fortress on a low hill during the Imjin War. Slanted stone walls still follow the slope, and from the top you look down over the Seosaeng coast. Private land and buildings sit inside, and restoration work continues. It makes an easy loop with some history on the side.
