Echizen Ono Castle, also known as Ono Castle and Kameyama Castle, is a hilltop style Japanese Castle in Ono Fukui Prefecture. Kanamori Nagachika ordered the construction of Echizen Ono Castle, which was completed in 1576. In 1586 Nagachika moved to Takayama Castle. In 1775 most of Echizen Ono Castle was destroyed by fire, although some parts were rebuilt in 1795, the donjon (tower) was not rebuilt. During the Meiji Restoration all the remaining building were dismantled. In 1968 a modern reconstruction of the donjon (tower) was completed. Echizen Ono Castle was just one of many castle built in the Echizen area.
