Ongözlü Köprü is an ancient bridge the crosses the Tigris south of the old walled city of Diyarbakır. It was completely reconstructed in the eleventh century/fifth century AH under the Marwanid rulers of Diyarbakır, having been destroyed during a Byzantine siege a century before. The bridge has ten arches or "eyes," hence its name Ongözlü, meaning "ten-eyed." The western five arches bear an inscription dating them to the 1060s/450s AH. These are slimmer than the remaining arches, suggesting that the eastern half was eventually rebuilt. Further restorations occurred during the last quarter of the nineteenth/first quarter of the fourteenth century AH.
