Ulsan Castle

Ulsan Castle is a Japanese fortification in Hakseong-dong built using traditional Japanese construction methods. The stone walls reach approximately 6 meters in height, and the complex contains several defensive structures distributed across the site.

In 1597, approximately 16,000 Japanese soldiers constructed this military stronghold over 40 days during their invasion campaign of the Korean Peninsula. The fortress was part of a broader strategy to secure control points along the southern coast.

The castle shows how Japanese soldiers maintained control over the southern Korean coast through military strongholds. Visitors can still see the remains of this defense installation that served as a key outpost during the occupation.

The site has limited accessibility due to surrounding urban development and is partially integrated into modern city structures. Visitors should coordinate with local authorities in advance to view the remaining structures and potentially join a guided tour.

The fortress received designation as Ulsan's seventh cultural monument, making it one of the few surviving Japanese military installations from the 16th century in Korea. This classification highlights its rare archaeological significance among the remaining defensive structures of that period in the region.
