The submarine exhibited in the Information Center is a 190-ton dolphin-class submarine that was responsible for infiltrating enemy lines, destruction, and patrol from 1991 to 2016. The right side of the Submarine, cut to make the interior of the complex wider and more secure, allows visitors to directly experience the inside and outside of the Submarine, while the deep-water images on the wall help visitors immerse themselves in the sea environment.

In the information center, visitors can enjoy photos and video exhibitions of 'Seoul Battleship Park, three warships and Han River.' The rooftop observation deck on the 3rd floor of the Information Center is a place to see the beautiful Han River and magnificent Frigate Seoul.
