France: Cahors – Pont Valentre
Cahors is famous for its UNESCO-listed bridge – Pont Valentre. Built in between 1308 and 1378, it has eight arches and three towers, looking like a fortress. The bridge is also know. As the Devils Bridge for the legend about the original architect having made a pact with a devil to have the bridge constructed in a very short time and then tricking the devil with payment (I guess it was the first municipal bond default). The devil then made sure that the construction would take place over 70 years to complete. When the bridge was renovated in 1878, the famous French architect Paul Gaut inserted a small sculpture of an imp on one of the tower to trick the devil into thinking that his minions are still working on damaging the bridge and this leave the bridge intact.
