A small village in Wales has changed its name from Llanfynydd to Llanhyfryddawelllehynafolybarcudprindanfygythiadtrienusyrhafnauole in protest against a wind farm which is planned for a nearby hill. They need to be careful - Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch got its full name when a tailor from Menai decided that they needed more tourists. Perhaps Llanhyfryddawelllehynafolybarcudprindanfygythiadtrienusyrhafnauole will stick.

(Llanhyfryddawelllehynafolybarcudprindanfygythiadtrienusyrhafnauole means "quiet beautiful village, a historic place with rare kite under threat from wretched blades" and beats Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch,
or "the church of St Mary in the hollow of the white hazel near the fierce whirlpool and the church of Tysilio by the red cave", in length by 8 characters.)
