A beautiful image of Nagoya Castle. You can see the donjon at the honmaru (inner citadel) and a small tower. The buildings in the foreground form part of the honmaru palace. The structures on the ends of the roof are golden shachihoko (金鯱), a mythical animal with a dolphin body and a lion head that protects the building from fire.
This image is extremely valuable because it shows what Nagoya Castle looked like during the Meiji Period (1868-1912), before many buildings were destroyed by the Mino-Owari Earthquake of 1891 (Meiji 24), or torn down.
