ARVANS (ST.), a parish, in the union and division of Chepstow, partly in the hundred of Raglan, but chiefly in the Upper division of the hundred of Caldicot, county of Monmouth, 2¼ miles (N. W. by N.) from Chepstow; containing, with the hamlet of Portcasseg, 354 inhabitants. This parish, which is washed on the north-east by the river Wye, and situated on the road from Monmouth to Chepstow, comprises by computation 2840 acres, and abounds in romantic scenery, which, in many situations, is of great diversity. From Piercefield Park, a splendid seat, the views are remarkably magnificent, and embrace numerous reaches of the Wye, the Severn, and a great range of the surrounding country. The mansion, situated on an eminence, in the midst of fine plantations, is a superb elevation of freestone, consisting of a centre and two wings, and much admired for its tasteful architecture: on the spacious staircase are four beautiful pieces of Gobelin tapestry which belonged to Louis XVI., representing subjects in the natural history of Africa. The living is a perpetual curacy; net income, £53; patron and impropriator, the Duke of Beaufort: about 50 acres of land of indifferent quality, contained in two small farms in other parishes, belong to the curacy. The church is in the early English style, with a square tower. Remains exist of two ancient chapels, dedicated respectively to St. Kingsmark and St. Lawrence: in the park, where is a chalybeate spring, are the remains of an encampment; and there is a small intrenchment in the hamlet of Portcasseg.
