The Japanese Government-General Building (often referred outside of Korea as the Seoul Capitol) was the chief administrative building in Keijo (Seoul) during the Japanese colonial rule of Korea and the seat of the Governor-General of Korea. It was a neo-classical building designed by German architect Georg De Lalande, and was completed in 1926. Although the building was later the scene of numerous important events for the Republic of Korea, housing first the National Assembly and later the National Museum of Korea, it was long felt to be a symbol of Japanese imperialism and was demolished between 1995 and 1996.
