Guinness Book of Records

The Domain Name Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch.co.uk was listed in the Guinness Book of Records in 2002.
At that time, the maximum number of characters allowed for an internet domain name was 58 (not including the suffix).
This limit was subsequently extended to 63, which, luckily, was exactly enough to enable the name of the upper part of the village to be registered. So an even longer domain name was registered with the 'uchaf' ending.
Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochuchaf.org.uk now holds the record as the longest valid (i.e. not made-up, such as abcdefg...etc.) domain name in the world.
The additional 'uchaf' signifies the upper part of the village. In the same way, the lower part of the village would be called Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochisaf.

Barbarella: 'You mean the secret password is Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch?'

Cure for Lockjaw

In around 1900-1910 a shrewd shopkeeper in the village was reputed to be selling "An English, Irish and Scotchman's cure for Lock-jaw", which comprised a sealed envelope with instructions inside. A copy of one of these cards is shown here (top image).

During same period, various tourist postcards appeared on sale, printed with a similar 'lock-jaw cure' theme, but appearing to target the 'Englishman' only.

This prank obviously exploited the fact that many tourists were unable to pronounce Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch correctly (Can you? Why not enter the 'Say the name competition?'
