TasKopru is a 4th-century bridge that was built by the Roman Emperor Hadrian in Adana Province. It is almost 320 meters in length and has 21 arches. In the middle arch, two lion reliefs can be seen. Harun Resit added some sections and connected the bridge with the Adana Castle during his reign. His son Memnun, Ottoman Sultan Ahmet III, Kel Hasan Pasha, and finally the Turkish government, in 1949, repaired it. It has been considered that Taskopru is one of the oldest bridges in the world that is still in use.
