Pont de Sainte-Catherine

Pont de Sainte-Catherine is a historical bridge in Plounévézel and Treffrin that has crossed the Hyeres River for centuries. The structure features three uneven arches built from blue-gray schist stone with four supporting piers and spans approximately 60 meters in length.

This bridge dates to the Gallo-Roman period and formed part of an ancient road connecting Carhaix to Lannion. It has endured for many centuries and is now protected as a classified historical monument.

Locals and visitors recognize this span as a distinctive landmark in the landscape, and its name references Saint Catherine, honored at this location. The straightforward, timeless construction reflects how people worked with their surroundings in practical, direct ways.

You can cross this bridge on foot and get good views of the river landscape from both sides. The path is flat and easy to navigate, though the surface is made of uneven ancient stonework.

What stands out about this bridge is its construction without mortar or cement, with stones arranged horizontally in corbelled arches that meet at the top. This ancient technique makes it a notable example of how craftspeople created stable structures using simple means centuries ago.
