The castle was originally built with 47 defensive turrets, a scale larger than many contemporary regional castles.
The stone walls utilize a construction method called 'uchikomihagi,' where stones are fitted precisely without mortar.
The castle grounds were intentionally designed to integrate with the sea, using the Hie River as a natural defensive moat.
The site features a preserved 'Shio-mi Yagura,' a watchtower historically used to monitor the tide.
The park contains the Fukuoka City Art Museum, which houses significant Buddhist statues and permanent collections.
The castle site was a key administrative center for the Kuroda clan throughout the Edo period.
Fukuoka Castle Ruins, also known as Maizuru Castle, are the remains of a massive stone complex constructed by Kuroda Nagamasa between 1601 and 1607. The site spans a large area within Maizuru Park, featuring extensive stone walls, moats, and restored gates including the Tamon Yagura. Most of the original wooden structures were demolished during the Meiji period, leaving behind the expansive stone foundation platforms. The highest point of the site offers elevated views of the modern Fukuoka city skyline. It remains a central urban green space designed around historic defensive fortifications. The grounds serve as a major location for seasonal flower viewing within the city. Visitors can explore the remnants of the defensive perimeter and several reconstructed guard towers.
