This building housing the Busan Modern History Museum was used as the Busan Branch of the Oriental Development Company during the Japanese occupation and as the Busan USIS Cultural Center (”An American CIA post”) following the Korean war. The exhibition consists of the modern history of Busan during the Japanese occupation, Busan’s role in the Korean war and the history of the relationship between Korea and the United States. Although not at all impartial, this museum nevertheless provides a fascinating background to modern Busan and you could probably spend two to three hours here.
