Overview

Saga Castle Ruins features a massive reconstruction of the Honmaru Palace, which is one of the largest wooden historic buildings in Japan. The original castle was constructed in the early Edo period by the Nabeshima clan. Today, the site functions as the Saga Castle History Museum, focusing on the history of the Saga domain and the Meiji Restoration. The facility utilizes tatami-matted halls and long corridors to recreate the atmosphere of the original palace. Significant portions of the original stone walls and wide water-filled moats remain intact around the grounds. The reconstruction project focused on architectural accuracy, utilizing traditional techniques and materials. Exhibits within the museum detail the modernization efforts of the Nabeshima lords. The grounds occupy the center of Saga City, serving as a public park space.
