The Roman bridge at Cendere, built by the Sixteenth legion Flavia Firma, is a remarkable monument. It is 118 meters long and was part of the road along the Upper Euphrates that had once been Rome’s eastern frontier, but had become a normal province after Septimius Severus‘ eastern conquests. The bridge has been in use for about eighteen centuries, and it was only very recently that a modern bridge was built next to it. Most tourists will pass along Cendere on their road to Nemrud dagi. I used to have a small page dedicated to this monument, but added twelve photos, available here.
