. The central castle building is five stories on the outside and eight stories on the inside, and built atop a tall stone foundation to protect its occupants from attackers. The Main Tower is surrounded by a series of moats and defensive fortifications. The castle has 2 moats (an inner & outer). The inner castle moat lies within the castle grounds, and consists of 2 types: a wet (northern-easterly) and dry (south-westerly). Outer moat meanwhile surrounds the entire castle premise, denotes the castle's outer limits, and consists of 4 individual water-filled sections, each representing a cardinal direction (North, East, South, West). The castle grounds, which cover approximately 61,000 square metres (15 acres), contain the following thirteen structures that were denoted as “important cultural assets” by the Japanese government: *Ote-mon Gate *Sakura-mon Gate *Ichiban-yagura Turret *Inui-yagura Turret *Rokuban-yagura Turret *Sengan Turret *Tamon Turret *Kinmeisui Well *Kinzo Storehouse *Enshogura Gunpowder Magazine *Three sections of castle wall all located around Otemon Gate *Megaliths at the castle include the Octopus stone. The outer moat has two main sentry checkpoints: the Aoyamon Gate (in the north-east) and the Otemon Gate (in the opposing south-west). Between the outer and inner moat are the following: Fushimi-yagura Turret Remains, Ensho-gura Gunpowder Storehouse, Osaka Geihinkan, Hoshoan Tea House, Osaka Castle Nishinomaru Garden, Sengan-yagura Turret, Tamon-yagura Turret, Remains of Taiko-yagura Turret, Osaka Shudokan Martial Arts Hall, Hokoku Shrine (Osaka), Ichiban-yagura Turret (The first turret), and Plum Grove. There are two places to cross the inner moat, Gokuraku-bashi Bridge (located in the North) and Sakuramon Gate (main sentry point in the South). Within the inner moat, the castle was divided into two major areas: the Hommaru (Inner Bailey) and the Yamazato-Maru Bailey. Located within the Hommaru is the Main Tower, the Kimmeisui Well, the Japanese Garden, the Takoishi (Octopus Stone), the Gimmeisui Well, the Miraiza Osakajo Complex, the Kinzo Treasure House, and the "Timecapsule Expo'70". While within the Yamazato-Maru Bailey consists of the Marked-Stones Square, and the Monument commemorating 'Hideyori and Yodo-dono committing suicide'.
