the capital of a county of the same name in North Wales, 158 miles from London, took its name from Roger de Montgomery earl of Shrewsbury, who built the castle. It is called by the Welsh Tra Valdwin, that is, Baldwin's town; having been built by Baldwin, lieutenant of the marches of Wales, in the reign of William I. The Welsh, after having put the garrison to the sword, demolished it in 1295; but Henry III. rebuilt it, and granted it the privileges of a free borough, with other liberties. It is a tolerably well built town, in a healthy situation and fertile soil, with 947 inhabitants in 1801.
