Göksu Koprüsü (bridge)

A short distance east of Dikilitas are the remains of a triple-arched bridge (centre arch, 31m/102ft, collapsed) over the Göksu, the ancient Singas, a tributary of the Euphrates. Up until the Middle Ages this was an important river crossing on the former military road from Samosata to Zeugma (60km/37 miles south-west of Adiyaman).
