En un regard
Le château en bref
Agi Castle (阿木城, Agi-jō) stands in the Agi district of Nakatsugawa (Gifu Prefecture), behind the Agi Hachiman shrine. This mountain castle (yamajiro) occupies the summit of Jōgamine, at 541 metres above sea level and some 60 metres above the surrounding area, across an enclosure of roughly 180 by 150 metres. Its founding date is uncertain: the city estimates that it existed by the late Sengoku period, in the 16th century at the latest. It may have been built by one of the two rivals who contested eastern Mino, Oda Nobunaga or Takeda Shingen, although this attribution has not been demonstrated. Large for the region, it retains remarkably legible earthen defensive structures, which still make it possible to understand the layout of a medieval castle. Designated a historic site of Nakatsugawa on 24 April 2002, it can be visited on foot by a forest path, about thirty minutes' drive from the Ena interchange.
