PRUDHOE-CASTLE, a township in the parish of OVINGHAM, eastern division of TINDALE ward, county of NORTHUMBERLAND, 12 miles (W.) from Newcastle upon Tyne, containing 79 inhabitants. Here was formerly a chapel, dedicated to St. Thomas. On an eminence sloping to the southern bank of the Tyne stood the castle, once the chief baronial seat of the Umfravilles; it has been long in ruins, but its ivy-mantled towers and lofty keep still remain, venerable monuments of its ancient grandeur and importance. Its present possessors are the Percy family, of whom Algernon, the only brother of the Duke of Northumberland, was created Lord Prudhoe, Baron of Pradhoe castle, in 1816.
