Odani Castle, Nagahama

Odani Castle was a Sengoku period mountain-top Japanese castle located in the former town of Kohoku, now part of Nagahama city, in Shiga Prefecture, Japan. Only the ruins remain today. It was the home castle of the Azai clan and the mountain it was built upon was considered to be impregnable. The castle fell during Oda Nobunaga's siege in the Genki and Tenshō eras, in 1573. Its ruins have been protected as a National Historic Site since 2005. ()
