Genbao Castle

Genbao Castle (玄蕃尾城) was a Sengoku period yamashiro-style Japanese castle located in the border area of what is now part of the cities of Tsuruga, Fukui Prefecture and Nagahama in Shiga Prefecture in the Hokuriku region of Honshu, Japan. It has been protected by the central government as a National Historic Site since 1999.

Background
Genbao Castle was built in 1583 on the peak of Mt. Uchinakao (460 meters) as the headquarters for Shibata Katsuie during the Battle of Shizugatake. The castle was built with features for both defensive and offensive operations, with the inner bailey at the highest point on the mountain, protected by earthen ramparts, dry moats and secondary enclosures. It is presumed that there was a tower by the remaining foundation stones in the northeastern corner of the inner bailey. Nothing remains of the castle today except for overgrown remnants of the moats and earthenworks.
