Pol-e Dokhtar
Pol-e Dokhtar takes its name from an ancient bridge over the Kashkan River in the mountains of Lorestan. The crossing lay on a road linking the Iranian plateau with Khuzestan and Mesopotamia. Massive stone piers and high arches carried travellers across the river near its junction with the Karkheh. Built on an ancient route, the bridge shows the importance of permanent crossings through the rugged Zagros valleys.
