an'gl-se, an island in the Irish Sea. It is separated from the mainland of North Wales by the Strait of Menai. It is about twenty miles long by seventeen broad, and is very productive, raising large crops of oats, barley, turnips, and potatoes. The central or more elevated portion of the island yields valuable copper, lead, and silver ores, besides limestone, marble, asbestos, marl, and granite. The interior affords excellent grazing for cattle and sheep. Welsh is the language of the peasantry. Anglesey, or rather the harbor of Holyhead, is the terminus at which railroad passengers from London take ship for Ireland. Trains cross Menai Strait to Anglesey, through the famous tubular bridge, a remarkable piece of engineering. The railroad track is laid inside of a huge steel tube supported on piers of masonry at a great height above the water. One of the finest suspension bridges in the world also crosses the strait. Its roadway is 580 feet in length from pier to pier and swings 100 feet above high tide . Large sea-going ships are able to pass under both bridges. The island of Anglesey was an ancient seat of the Druids. A Druidical pontiff lived in security here, and a Druidical college was located on the island. Agricola subdued the Druids in the year 85 A. D. See British Isles 2026 Editor's Note: Anglesey is now best known for a linguistic joke turned tourist magnet: the village with the longest place-name in Europe, Llanfairpwllgwyngyllgogerychwyrndrobwllllantysiliogogogoch, whose railway sign draws photographers from around the world. Thomas Telford's pioneering Menai Suspension Bridge still links it to the mainland. (Ed: BR 2026-07-13)
