I believe the change was by the railway company so it could boast the longest station name in the country, and achieved by extending the town's proper name. "Llan" means 'town' or 'settlement': much of the rest, in a language that puts the adjective after the noun as in French, is a list of geographical features.
Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch or its english translation of; St Mary's Church in the Hollow of the White Hazel Near to the Rapid Whirlpool of Llantysilio of the Red Cave.
