Seosaengpo Castle, Japanese fortress in Seosaeng-myeon, South Korea
The castle structure rises 15 meters high on a mountain slope, featuring a rectangular layout with citadels at three different elevations reaching 200 meters.
General Katō Kiyomasa constructed this strategic fortress between 1592 and 1593 during the Japanese invasion of Korea known as the Imjin War.
The fortress stands as a material record of Japanese military architecture in Korea, designated as a cultural asset by Ulsan Metropolitan City.
Visitors can reach the castle by taking bus 1003 to Gijang Catholic Church, transferring to bus 180, then catching Ulsan bus 175.
Sections of the original castle walls now function as foundations for residential buildings, integrating historical architecture with modern construction methods.
