Early History

The village development saw the establishment of a Post Office, two schools, half a dozen pubs, a brewery, a hotel and (by 1889) 12 grocers. The village by then had a population of 961. In 1894 a livestock market emerged, and a slate factory opened in the nearby harbour of Pwllfanogl. In the 1960s and 1970s the "new" village began to appear. There was extensive building on various sites, and the population increased from 1,172 in 1961 to 3,101 in 2011. Llanfairpwll still retains its village atmosphere, even though there are more people living there than in many other towns in Wales.

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, and so the domain name was extended with 'uchaf'.
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' refers to the upper part of the village. In the same way, the lower part of the village would be called Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogochisaf.
