The bridge, built in 1268 on a design by Mastro Bentivegna, unique in its shape throughout the course of the Chienti, has five arched arches supported by powerful pylons, with a quadrangular tower-barrier, crenellated to the Guelph.Its name of "Devil's Bridge" comes from a legend common to many bridges scattered throughout Europe.A modern plaque is affixed to the wall of the tower, instead of the original one, for which the bottom of a Roman sarcophagus was used. (Part of the plaque is now preserved in the lapidary at the Basilica of St. Nicholas).In 1524, by resolution of the Municipality, a sacred aedicule was erected on the edge of the central pylon that still remains, with a fresco representing the Virgin and Child.On June 30, 1944, during world war II, retreating German troops blew up the central arch of the bridge, which was later rebuilt in its original form.In front of the arch of the bridge tower stands the door of the bridge from which the imposing walls begin.
