As the heart of the castle town area, the castle serves as a symbol of the long-standing history of Nakatsu.
The history of Nakatsu Castle began with the construction by the famous Sengoku-period strategist Kuroda Kanbei (also known as Kuroda Takataka). Following his work, the castle was completed by Hosokawa Tadayoki.
