MACHYNLLETH (MACHYNLLAETH), a market-town and borough and parish (comprising the three townships of Machynlleth, otherwise Y Dre, Is-y-Garreg, and Uwch-y-Garreg), and the head of a union, in the lower division of the hundred of MACHYNLLETH, county of MONTGOMERY, NORTH WALES; and containing 2482 inhabitants, of whom 1636 are in the township of Machynlleth, 39 miles (W. by N.) from Montgomery, and 209 (W. N. W.) from London. This place, which is of considerable antiquity, is supposed to have been the site of the Maglona of the Itineraries, a Roman station, where, in the reign of the Emperor Honorius, the captain of the 44 Numerus Solensium" was posted, under the Dux Britanniarum, to keep the mountaineers in subjection. Connected with the principal station, which occupied the highest part of the hill, was an outwork called Cevn Caer, or " the ridge of the city," about four miles from the present town, in the adjoining parish of Pennal, in the county of Merioneth, of which there were formerly some remains, and at which place several Roman coins have been at various times discovered. From the departure of the Romans till the time of Henry IV., few circumstances of historical importance connected with the place are recorded. In 1402, Owain Glyndwr,
