Did you know that the longest official one-word placename in Europe is in Wales, UK? Its name is Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch and has 58 letters. It means “Saint Mary’s Church in a hollow of white hazel near the swirling whirlpool of the church of Saint Tysilio with a red cave”.
In the following video you can see how a weather presenter nails it when pronouncing it!
Just if you want to know, the longest official placename in the world according to the Guinness World Records is in New Zealand and it is called: Taumatawhakatangihangakoauauotamateaturipukakapikimaungahoronukupokaiwhenuakitanatahu with 85 letters and it means “The summit where Tamatea, the man with the big knees, the climber of mountains, the land-swallower who travelled about, played his nose flute to his loved one”
Needless to say, these two places have their short form… I guess pronouncing and writing them in their full form must be quite a challenge!
