PETERSTON-super-ELY, a parish, in the union of CARDIFF, hundred of DINASPOWYS, county of GLAMORGAN, SOUTH WALES, 7 miles (W.) from Cardiff; containing 223 inhabitants. This parish, which derives its name from the dedication of its church to St. Peter, and its distinguishing adjunct from its situation on the bank of the river Ely, lies in the south-eastern part of the county, and comprises a moderate portion of arable and pasture land, in a good state of cultivation. Limestone is found in most parts of the parish, and the procuring of it affords employment to a portion of the inhabitants. The living is a rectory, rated in the king's books at £7. 12. 8f.; present net income, £228; patrons, Sir T. D. Aubrey and Col. Wood. The church, dedicated to St. Peter, is not distinguished by any architectural details. A day and Sunday school affords instruction to about twenty children; the day school is partly supported by subscriptions from the rector and curate, and partly by small payments from the parents; the Sunday school is maintained wholly by the rector and curate. There are in the parish the remains of an ancient castle, which has been long in ruins; but nothing satisfactory is known of its original foundation.
