Devils bridge

Normally called "Ponte della Maddalena" (Magdalena's bridge, build in the era of the Countess Matilde di Canossa 1046-1115) in Borgo di Mozzano.

It has got it's name by a popular legend: The architect who was about to build this bridge could not finish the construction until the date of delivery. So he called the help of the Devil itself who agreed to finish the bridge in one night in exchange for the soul of the first person to cross the bridge the next day.
The architect instead sent a pig (or a dog, the myth is quite blurry in this point). Being fooled that way the devil threw himself into the river bending it to it's present shape.

Take a look at the bridge.
