a town of Wales, and capital of the county of that name. It was built by Edward I. near the site of the ancient Segontium. It is almost surrounded by the sea and two rivers; gives name to the neighbouring bay; and had anciently a castle, built also by Edward I. in which his son Edward II. was born. It is a small neat town, governed by a constable of the castle who is also mayor, an alderman, two bailiffs, a town-clerk, and other inferior officers. The market is well supplied with provisions, and there is a ferry from hence to Anglesey. The town gives title of earl and marquis to the duke of Chandos, and has a good tide-harbour.
