Small castle ruins preserving the history connected to Oda Nobunaga

About this spot

A historic site said to have been the location of the residence of the Iwakura Oda clan, which ruled this region during the Sengoku period. While no buildings from that era remain today, through signs and historical markers, you can trace the history of this region deeply connected to Oda Nobunaga. Despite its compact size, it's an essential spot for understanding how the town of Iwakura was formed.
