@osmanli_tarihi_61: Şeytan Kalesi is a medieval fortress near Çıldır, Ardahan Built on a narrow rocky ridge above a deep canyon Its earliest roots go back to the Urartian period while the visible remains mainly date to the medieval era When it was used by Georgian and Byzantine rulers The castle guarded key routes between Anatolia and the Caucasus Steep cliffs made it extremely hard to attack so nature itself acted as its main defense The name “Devil’s Castle” comes from its frightening landscape Not from any legend #osmanlıtorunu #tarih #ardahan75 #erzurum #osmanlı
