秋の「国指定史跡 岡城跡」
撮影：2023.11.17

全体的に6～7割くらいの色づきでしょうか。

綺麗に色づいてる木々もちらほら。　風情があって美しいですね。

難攻不落、天然の要塞として有名な岡城。

岡城は、阿蘇山の火砕流でできた海抜325mの岩山に建っていました。

大野川の支流、稲葉川と白滝川に挟まれた舌状台地上に築かれた岡城は、周囲は断崖絶壁に囲まれ、更にその絶壁上が石垣で囲われた堅城。広さはなんと100万㎡で、東京ドームの22個分あります。

明治時代の廃城令で現在は建物がありませんが、この圧巻の広さや石垣群、そして城跡から眺めるくじゅう連山や阿蘇山、そして祖母山の絶景は訪れる人たちを感動させます。

National Historic Site "Oka Castle Ruins” in in autumn

Overall, the autumn foliage at the ruins of Oka Castle is about 60-70%. Some trees are beautifully colored.

Oka Castle is famous as an impregnable, natural fortress.

Oka Castle was built on a rocky hill 325 meters above sea level, created by pyroclastic flows from Mt.Aso.

Oka Castle was built on a tongue-shaped plateau between the Inaba and Shirataki Rivers, tributaries of the Ono River. Surrounded by precipitous cliffs, the castle was a solid fortress with a stone wall on top of the cliffs. The area is 1,000,000 square meters, which is equivalent to 22 times the size of Tokyo Dome.

Although there are no buildings there today due to the Meiji Era (1868-1912) decree abolishing the castle, the impressive size, the stonewalls, and the spectacular view of Kuju mountain range, Mt.Aso and Mt.Sobo from the ruins of the castle are sure to impress visitors.
