Iğdeli Castle, locally known as Iğdeli Kalesi, lies on a mountain north east of the village of the same name, in the province of Erzurum in Turkey.
I was not able to find any historical information whatsoever about Iğdeli Kalesi. So, if you know more, please mail me.
Iğdeli Kalesi, built out of rubble masonry, consists of an upper and lower castle, connected by a defensive wall over a ridge. Although you can enter the upper castle, the lower castle is inaccessible. North west of the castle is a rather flat area of the mountain which, I think, acted as an outer bailey, were there are a ruin of a chapel and some small wall parts.
Iğdeli Castle is freely accessible although there is no distinguishable path to it. A beautiful castle, too bad there is some kind of cement factory at the feet of the mountain.
