Devil's Bridge is a term applied to dozens of ancient bridges, found primarily in Europe. Most of these bridges are stone or masonry arch bridges and represent a significant technological achievement in ancient architecture. Due to their unusual design, they were an object of fascination and stories in antiquity and medieval Europe.
Each of the Devil's bridges typically has a corresponding Devil-related myth or folktale regarding its origin. These stories vary widely depending on the region and beliefs. Some have the Devil as the builder of the bridge, relating to the precariousness or impossibility of such a bridge to last or exist in the first place, so much so that only the Devil himself could have built it. Others have the knowledge to build such bridges given to mankind as a gift from the Devil as part of a deal, pact or bargain between the Devil and local populace, usually in exchange for their souls.
