5Saga Castle in the early Edo Period

This diagram is a detailed depiction of Saga Castle in the early Edo Period. Saga Castle, surrounded with a moat roughly 70 meters in width, is quite large compared to other castles in Japan, belonging to the same class as Himeji Castle and Nagoya Castle. If you look at the map, the main palace, where you are standing right now, is drawn on the lower right, and you can also see the five-storied watchtower beside it.
