The Devil’s Bridge is a medieval bridge over the Arda river.
The bridge was built in 1515 - 1518 by the builder Dimitar from the village of Nedelino (which is a town nowadays) upon the remains of an ancient Roman bridge on the road, linking the Aegean region with Northern Thracian valley (Gornotrakiyski Nizina) through the Makaza pass.
Legend says that the Devil himself took part in the construction of this bridge. During the middle ages, the Arda river was extremly wild and turbulent. Many had tried to connect the two banks of the river, but they all failed. Until a determined and ambitious young man appeared. He decided to build a bridge across the river no matter what it would cost him. Suddenly, the Devil appeared before him and promissed to reval the secret of how to make a bridge that would last forever. The Devil demanded from the builder to incorporate his demonic face in the bridge in a way that would be visible and invisible at the same time. The young man had 40 days to accomplish this task. If he failed the Devil would take his soul to Hell. Surprisingly, the builder managed what the Devil told him before the deadline. The bridge still stand exactly as it was 500 years ago and if oyu look closer, you will notice the ominous appearance of Satan.
