On the southeastern coast of Anglesey, an island off the coast of mainland Wales, lies a little town with a big name. Following a Welsh tradition of naming towns after churches and nearby geographic features, Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch roughly translates to “St. Mary’s Church in the hollow of white hazel near a rapid whirlpool and the Church of St. Tysilio near the red cave.”
Though Wales has many towns with long names, the unusual length of this one is intentional. The settlement, now home to about 3,000 people, was once called Llanfairpwllgwyngyll, but a local resident pushed for the longer version of the name in the 1860s as part of an effort to promote tourism and give its train station the longest name in Britain. Locals usually use a short version of the name—either Llanfairpwll or Llanfair PG.
The OLI (Operational Land Imager) on Landsat 8 captured this image of the town on April 9, 2025. The image below shows a wider view of the same area. The whirlpool mentioned in the name likely refers to a section of the Menai Strait between the Menai Suspension Bridge and Britannia Bridge known as the Swellies. The area is known for having exceptionally treacherous waters because of its complex bathymetry and because tides enter the strait from both ends at different times, creating strong swirling currents. Menai Suspension Bridge, often described as the first modern suspension bridge, was completed in 1826.
