iOpened in 2001 on the site of the ancient Naniwa Palace, the museum tells Osaka's story over four floors, from the ancient period on the 10th floor down to modern and contemporary Osaka on the 7th. The 10th floor holds a full-size reconstruction of the palace's Daigokuden hall, the 8th floor a full-scale excavation site, and the 7th a life-size panorama of the modern city. Palace remains can be seen in the basement. It stands across from the southwest corner of Osaka Castle Park and is a separate institution from the Osaka Castle Museum.
