Description
Located nearly due east of Odawara Castle (Kanagawa Prefecture, Japan), this photo shows a moat and stone wall (left), and turret or guard tower (right) near the Umademon Gate (馬出門, lit. horse exit gate) to the castle. Behind the wall is another gate that led to the livery stables of the castle. The moat, gates, and walls were designed to force troops through a zigzag pattern before reaching the keep as a defense measure should the castle come under attack.
