The Korean Naval Academy Museum was opened on January 17, 1976, on the 30th anniversary of the Korean Naval Academy. When it first opened, the museum consisted of only a small exhibition room, but later saw the addition of a life-sized, ironclad Geobukseon (turtle ship) on January 31, 1980. On February 23, 1981, an independent museum building was opened at the site and on April 28, 1990, the museum was expanded to its current size.The museum (2,622 square meters in total area) is housed in two separate buildings (a two-storey building and a three-storey building) and boasts three exhibition halls (Yi Chungmugong Hall, Navy Hall, and Naval Academy Hall). The Yi Chungmugong Hall has on display 212 materials relating to the life of the famous Korean navel leader General Yi. At the Navy Hall, the history of Korea’s Navy is on display. The history of the naval academy itself is celebrated at the Navy Academy Hall through the presentation of 315 artifacts. In the outdoor exhibition area, visitors are met by a life-sized turtle ship, cannons, and old anchors from the Joseon Era, as well as an S2 anti-submarine plane and an amphibious armored car used during the Korean War.
