The park contains the city wall and the castle skyshou pavilion in the middle, which covers an unexpectedly large area and is really surprising and moving. In the middle of the castle is a museum that introduces the history of the castle and the history of Osaka's summer and cultural relics. It is recommended not to take the elevator, walk upstairs, and watch the museum cultural relics layer by layer. The top floor is open to tourists to enjoy the view of Osaka city and take pictures from the balcony. If you want to enjoy the ontology of Osaka Castle, look out from the Osaka History Museum opposite, it is also a good location.
