A view, with artistic license, of Devil's Bridge in Ceredigion in central Wales. From Wikipedia: "The bridge spans the Mynach a tributaryof the Rheidol. The bridge is unusual in that three separate bridges are coexistent, each one built upon the previous bridge. The most recently built is an iron bridge (1901), which was built over a stone bridge(1753), which was built when the original bridge was thought to be unstable. The builders of the 1753 bridge used the original bridge (built 10751200) to support scaffolding during construction."
