Marugame Castle丸亀城[ Marugame jyo ]

Marugame Castle (丸亀城, Marugame-jō), also known as Kameyama Castle and Horai Castle, is a hirayamashiro (castle situated on a hill surrounded by a plain) located in Marugame, Kagawa Prefecture, Japan. The first fortifications built on the site that would later become Marugame castle were erected by the Nara clan led by Nara Motoyasu, who in turn were retainers of the Hosokawa clan during the Muromachi Period. Little evidence of this exists today, however.
