<jats:title>Abstract</jats:title><jats:p>Although research is currently impossible on the ground, satellite photographs allow some further information to be gleaned concerning the region of the Tur Abdin, of crucial importance during the wars between the late Roman Empire and Sassanian Persia in the fourth to seventh century AD. This article examines the ancient sources and the reports of visitors to the area in the light of what is now visible to all via Google Earth and other suppliers of free satellite imagery. Apart from describing the remains of the fortresses and their role in defending an important redoubt against Persian attacks, it draws attention to the urgent necessity for proper ground surveys of what remains of the fortifications of various periods before these are completely destroyed by looting and reuse of building materials. Dams also present a substantial risk to some of the monuments discussed here.</jats:p>
