Llanfair PG is the usual name for a village on the Isle of Anglesey, off the coast of North Wales.
It is famous for its very long full name, the longest in the world. This full name is Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.
Does it mean anything? It certainly does. The translation into English is "St. Mary's Church by the white aspen over the whirlpool and St. Tysilio's Church by the red cave".
The long name was invented in the late 19th century as an early, and very successful, attempt to attract tourists.
The first Women's Institute was formed here.
