Seoulham Park sits along the Han River and displays a naval vessel that completed 30 years of territorial sea defense missions. Visitors can go inside three actual military ships: the Seoulham, a Chamsuri-class patrol boat, and a Dolgorae submarine. On the Seoulham, the bridge, officers' quarters, sailors' quarters, and dining hall are open to view. Apart from the ships, there is little else to see.
