Origunally called Agata Castle, Nobeoka castle was never very big and didn't even have a keep, ony a three-story turret that only lasted 30 years before burning down.
Built on a small hill at the junction of two rivers, a succession of clans controlled the castle with the Naito holding it until the castle was decommissioned in 1870.
There are no buildings left but the gate was rebuilt in 1993. Like most castle ruins the grounds are now planted in cherry trees.
a more than twenty meter high wall supposedly would collapse and crush 1,000 attackers should a single keystone be removed. Saigo held the castle briefly in 1870.
Now it is a popular ohanami spot.
