Kanazawa Castle 金沢城
In this complex, the three-story Hishi Yagura and Hashizume-mon Tsuzuki Yagura are connected by the two-story Gojukken Nagaya. These buildings were originally designed to protect Ni-no-maru, the second enclosure, in case of a battle. Therefore, they have features for defense, such as "ishi-otoshi" for dropping stones, and fire-proof walls which contain hidden holes for shooting.
