Divriği is a town and a district of Sivas Province of Turkey. The town lies on gentle slope on the south bank of the Çaltısuyu river, a tributary of the Karasu river.During the Byzantine period the town, then called Tephrike or Tephrice, was an important stronghold for the Paulicians.The medieval (13th century) castle remains still exist on top of a steep hill.
