Fukuoka Castle is situated adjacent to Ohori Park in Maizuru Park and features the remaining stone ramparts and walls left after a devastating fire during upheaval of Meiji Restoration. It has been preserved together with some reconstructed concrete towers constructed during 1950s-1960s, when there was a trend to rebuild damaged castles as attractions for tourists. Ōhori Park is the location of one of the major art galleries in Fukuoka City. A newly opened Kyushu National Museum is found in nearby Dazaifu.
