The Devil's Bridge (Pont del Diable)

In the heart of the village of Cardona in Catalonia, Spain, you’ll find the Bridge of the Devil - or Pont del Diable, in Catalan. This incomplete bridge dates back to the 15th century, though some sources suggest it's even older. The bridge was built as part of the Camì de Sant Jaume, a road that centuries-old pilgrims used to reach key religious sites such as the Monastery of Montserrat, the Basilica of Pilar of Saragossa, and Santiago de Compostela.

Yet, despite its historical significance, this bridge is incomplete - a tale of ambition and misfortune. Architecturally, the bridge consists of two arches of varying width and height, each resting on rocks of the riverbed, forming an obtuse angle. It's 59.25 meters long, with the larger arch having a diameter of 25.50 meters, a height of 24.30 meters, and a thickness of 1 meter. The smaller arch has a diameter of 15.80 meters, a height of 21.50 meters, and a thickness of the same 1 meter.

The bridge was constructed using square carrers arranged in horizontal rows and connected with lime mortar. A motto is engraved at the base of the internal support of the arches. The first written record of the bridge dates back to October 28, 1424. Construction was initiated due to the dangerous crossing that the river Cardener represented for the pilgrims on their way to the aforementioned destinations.
