The village stands near the Chester and Holyhead railway, and near the Menai strait, 5 miles SW of Beaumaris; takes the latter part of its name, signifying "raging-pool," from the Swelly rocks whirlpool in the strait; and has a station, of the name of Llanfair, on the railway, and a post office, of the name of Llanfair-Pwllgwyngyll, under Bangor.The parish contains also the small seaport of Pwllfanog. ...
