Llanfairpwll
Llanfairpwll's claim to fame is that it has the longest village name in Britain, although it was originally simply called Llanfairpwllgwyngyll. In Victorian times, someone had the inspired idea of creating a new and record breaking name for the village to boost its attraction as a tourist venue, and that decision was clearly right, as evidenced by the tourists who continue to visit in large numbers to this day.
The record-breaking name is Llanfairpwllgwyngyllgogerychwrndrobwll-llantysiliogogogoch, which translates as St Mary's Church in the hollow of the white hazel near a rapid whirlpool and the Church of Saint Tysilio near the red cave. It is commonly abbreviated to Llanfair P.G.
