Llanfairpwllgwyngyll or Llanfair Pwllgwyngyll is a village on the island of Anglesey in Wales, Britain. It is in the Guinness Book of Records for being the place with the longest name in Britain. The village is also known as Llanfair PG or Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.
The name means "St Mary's church in the hollow of the white hazel near to the fierce whirlpool of St Tysilio of the red cave" in Welsh. It was invented in the 1860s by a local tailor to make the village famous for having the railway station with the longest name.
English speakers (pronounce ch as in "Loch-Ness") saying "Thlan-vire-poothl-gwin-githl-go-ger-igor-chwen-drob-oothl-landus-ilio-goh-goh-goch" will sound close to how it is meant to sound although the double L sound is difficult to recreate.
The population is about 3,000.
