İslamköy is a village in the District of Kahta, Adıyaman Province, Turkey.
The village corresponds to ancient Alia, which was in the Roman province of Phrygia Pacatiana, whose capital was Laodicea on the Lycus. The names of some of the bishops of Alia are known through their participation in church councils: Caius at the Council of Chalcedon (451), Glaucus at the Second Council of Constantinople (553), Leo at the Second Council of Nicaea (787), and Michael and Georgius, the one a supporter of Patriarch Ignatius of Constantinople, the other a supporter of Photius, at the Council of Constantinople (879).
No longer a residential bishopric, Alia is today listed by the Catholic Church as a titular see.
