In Wales, is a small village named Pontarfynach, meaning “the bridge on the Mynach”. But its name is a little bit of a misnomer: there are actually three bridges!
The original and the lowest bridge was built in the 1000s CE. When that was thought to be unstable, a second stone bridge was built over the gorge directly atop the original bridge. That was in the mid-1700s century. The original bridge was not demolished; rather it was used to support scaffolding during construction. The third and the final bridge is an iron bridge constructed in 1901.
