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 was built and on April 28, 1990, the museum was expanded to its current size.
