CEMMES (CEMMAES), a parish, in the hundred of MACHYNLLETH, county of MONTGOMERY, NORTH WALES, 7 miles (N. E. by E.) from Machynlleth, containing 917 inhabitants. The name of this place signifies a circle, or amphitheatre for games. The village is pleasantly situated on the southern bank of the river Dovey, and on the road from Welshpool to Machynlleth and Aberystwith, which, from a short distance north of it, runs parallel with the river for the remainder of its course. From Moel Eiddan there is a fine view of the vale of Cemmes and Mallwyd, through which winds the Dovey, bounded by the extended bases and lofty summits of Ceder Idris, Aran Mowddy, Plinlimmon, and other hills. About one-third of the parish consists of sheep-walks belonging to the adjoining landowners: peat for fuel is obtained within its limits. Fairs are held on May 1st, September 9th, and November 24th. The living is a rectory, in the archdeaconry and diocese of St. Asapb, rated in the king's books at £7, and in the patronage of the Bishop of St. Asaph. The church, dedicated to St. Tydecho, is in the early style of English architecture: the gallery is adorned with fine carvings of flowers, &c., in wood; in the churchyard there are four large yew trees. There are places of worship for Independents and Calvinistic Methodists. A Welsh circulating school is at present (1831) situated at this place, for an account of which See DAROWEN; and it is in contemplation to establish a National school. There is a Sunday school in connexion with the church, in which about sixty children are instructed. A small plot of ground was bequeathed to the poor by Derwas Griffith, in 1669; the sum of £40 by Bridget Mostyn, in 1730; and £20 by Grace Pryse, in 1784. Upon the summit of Moel Eiddan are the remains of a Roman encampment; and in a turbary near it, a brazen celt, and a circular ornamented brooch of brass, about three inches in diameter, were found, in 1824, which are now in the possession of the Rev. Isaac Bonsall, rector of Llanwrin. The poor are supported by an average annual expenditure amounting to £474. 14.
