Sagiyama Castle ruins is located in Gifu City. The castle was Saito Dosan's last place of residence before he was killed in the Battle of Nagaragawa in 1556. Sagiyama Castle could be known as Dosan's retirement castle as his son Yoshitatsu occupied Inabayama Castle (Gifu Castle). Also Nobunaga's wife, Nohime spent considerable time at Sagiyama and the chances are high that she was born there.
