At the entrance to town a single arched bridge called Pont du Diable(because it was thought that only the Devil could build such a thing)was built in 1321. The bridge crosses the Tech River, which is rocky and can be tumultous. It would be difficult to cross without a bridge. The architect is said to have made a deal with the Devil to build the bridge. The Devil requested the soul of the first Ceretan who walked across as his reward for helping the architect build through the rocky river. The engineer who built it first tried to send a cat over but the trick backfired as then none of the locals would use it for fear of incurring the Devil's wrath. Supposedly the architect tricked the devil and made him so mad that he attempted to tear down the bridge.There is even a carved stone placed there by the restorer showing the Devil trying to tear out the stones.
The bridge became famous in later years as a refuge for escapees from Franco's fascist regime, with many famous artists passing through or spending time here.
Whatever its origins, it is a beautiful bridge that provides a breathtaking view of the river and valley below.
