Daphne was a Byzantine fortification inaugurated, most probably in 327, on the left bank of the Danube, across Transmarisca, in the delta of the Arges river. In 367, emperor Valens crossed the Danube at Daphne using a pontoon bridge. It was mentioned by Ammianus Marcellinus and Procopius of Caesarea.
