Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch. It is the Welsh name of a small town on the Island of Anglesey, off the North Wales coast. It is usually shortened to Llanfair.
Translated it sort of means ” St Mary’s Church in the Hollow of the White Hazel near a Rapid Whirlpool and the Church of St. Tysilio near the Red Cave”. Yes, I can pronounce it correctly, if anyone is wondering.
