琴平金刀比羅宮に続く参道22段目に佇む温泉旅館「桜の抄」

Marugame Castle , also known as Kameyama Castle and Horai Castle, is a hirayama shiro (castle situated on a hill surrounded by a plain) located in Marugame, Kagawa Prefecture, Japan.
 
Besides the stone walls, few of the buildings at Marugame Castle stand today. The Ote Ichino Gate, Ote Nino Gate, and the tenshu, which underwent a major restoration in 1950, remain. These original buildings have been declared Important Cultural Properties by the Japanese government. Marugame Castle is one of only a dozen Japanese castles to have an original wooden tenshu built before 1860.
The castle is preserved in Kameyama Park, and its museum is housed in the tenshu.
