Also known as the Dicle Bridge (Dicle Köprüsü) or the Silvan Bridge, the On Gözlü Bridge (On Gözlü Köprü) was constructed during the reign of Nizamüddin Nasr in the Marwanid period between 1065 and 1067, per its inscription. The ten-arched bridge was built entirely of hard volcanic basalt stone and rubble stone. It is 18 meters long and around six meters wide. Engraved into the basalt stone next to the inscription is a relief featuring a right-facing lion relief in a frame. Some small marks can be found on adjacent stones, which feature the camel bridge body of the lion figure. Over time, the bridge underwent destruction from enemy armies but was later repaired. Today, there is a restaurant serving the city’s distinguished flavours and local cuisine, as well as a cafe section where iwan nights are held – this area attracts both domestic and foreign tourists.
