Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch meaning Saint Mary's Church in the hollow of the white hazel near a rapid whirlpool and the Church of St. Tysilio of the red cave.
The town was originally called Llanfairpwllgwyngyll but had the extra letters added on in the late nineteenth century, some say as an early publicity stunt to attract tourists. It certainly worked as the small town on the island of Anglesey just off the North Wales coast is a popular tourist destination, everyone wanting to have their photo taken with the famous railway sign.
If you ever visit Wales you'll find hundreds of places beginning with Llan, which means church, such as Llangollen, (church of Collen), Llandeilo (Teilo), Llanmadoc (Madoc) and so on.
