The Bridge of Arta is a stone bridge that crosses the Arachthos river in the west of the city of Arta in northwestern Greece. It has been rebuilt many times over the centuries, starting with Roman or perhaps older foundations; the current bridge is probably a 17th-century Ottoman construction.
The folk ballad "The Bridge of Arta" tells a story of human sacrifice during its building. From the ballad, a number of Greek proverbs and customary expressions arose, associated with interminable delays, as in the text of the ballad: "All day they were building it, and in the night it would collapse."
