The Çaltısuyu, a tributary of the Euphrates, flows through the dramatic canyons of eastern Anatolia. At around 1,225 meters above sea level, it emerges onto a barren highland plateau overlooked by the crumbling remains of a medieval castle. The small town of Divriği lies on the gentle slope beneath. Although its ornate thirteenth-century mosque has been recognized as a UNESCO World Heritage Site, few tourists make the journey to this remote and mountainous region.
Accessibility is usually something of a prerequisite for the establishment of a new town. Quite the opposite was true for Divriği. This site was first settled around the middle of the ninth century CE by a group of religious dissidents known as Paulicians.
