勝山館跡 / The Site of Katsuyama Castle

勝山館跡（位於上之國町）是從中世紀開始就存在的遺跡，被指定為史跡以及重要文化財。據說是一位名叫武田信広的武將平定這塊土地之後，在1473年時築城（當時，武田便將姓氏改名為蠣崎）。勝山館一直使用到16世紀中期左右，之後由信弘的兒子蠣崎光広來繼承，然而因為根據地必須要轉移，這裡便成為臨時的城池。

The Site of Katsuyama Castle (Kaminokuni Town) is designated as a historic landmark of Japan, and an important cultural property which shows us historical events of medieval times in Hokkaido. Takeda Nobuhiro, a lord and a warrior, governed here, and the castle seemed to be commissioned by him in 1473. At the time, he changed his family name from Takeda to Kakizaki. Katsuyama Castle was used until the middle of the 16th century by Kakizaki Mitsuhiro, a son of Nobuhiro. Nobuhiro moved to another base and the place grew quiet, with the castle only being used sporadically.
