THE STORY

The story behind the walls

The castle was completed in 1611 as the Nabeshima seat. It remained the political centre of Saga Domain through the Edo period. Nabeshima Naomasa rebuilt the main palace in 1838. Much of it was later lost, but the Gozanoma survived after relocation. In 2004 a wooden reconstruction of part of the palace opened as a prefectural museum, with the original room returned to the site.

LAYOUT & ARCHITECTURE

Read the landscape and the buildings.

Broad moats surrounded the lowland castle; today the main palace provides its principal interior experience. Traditional joinery and wall construction were used to recreate connected tatami halls and corridors. The original Gozanoma, returned from another location, is historic fabric within the wider reconstruction.

A CLOSER LOOK

Details worth a closer look.

01

Wooden main palace

Traditional construction methods were used in the reconstruction. It recreates the palace of government and residence, rather than a keep.

02

Large tatami hall

Expansive rooms and a long tatami corridor convey the scale of the palace. The connections between rooms reveal the palace’s internal organisation.

03

Original room and gate

The lord’s original Gozanoma was returned from another site; Shachinomon Gate also survives. The site allows comparison between new reconstruction and Edo-period fabric.
