Le château en bref
Iinoya Castle (井伊谷城, Iinoya-jō) is located in Iinoya, Inasa-chō, in Hamana Ward of Hamamatsu, Shizuoka Prefecture. This hilltop castle (yamajiro) overlooks the Iinoya Valley, between the Iinoya and Jingūji rivers. Its founding is traditionally attributed to Ii Tomoyasu in 1032, a date not confirmed by archaeology. In peacetime it served as the residence of the Ii clan, while Mitake Castle acted as the main fortress. In the 16th century it is associated with Ii Naotora, and it was caught up in the struggles between the Imagawa, the Tokugawa and the Takeda, notably around 1568–1573. Earthworks and stone walls are recorded at the summit, and areas known as the honmaru and Nijōmaru lie at the southern foot. Designated a historic site of the city of Hamamatsu on 26 August 1985, it has been developed into a public park, Shiroyama Kōen, which is open free of charge and a fifteen-minute walk from the local heritage centre.
