Pont de Sainte-Catherine, Roman bridge in Plounévézel and Treffrin, France
The Saint Catherine Bridge spans 60 meters across the Hyeres River with three uneven arches and four spurs made of blue-gray schist stones.
Built during the Gallo-Roman period in the third century, this bridge formed part of the ancient Roman road connecting Carhaix to Lannion.
The bridge represents early French engineering techniques with its dry stone construction method and triangular arches topped by flat stone slabs.
The structure measures 60 centimeters in width and features protective parapets that rise 40 centimeters above the bridge deck.
The bridge maintains its original construction with stones placed horizontally in corbelled arches, meeting at the top without mortar or cement.
