RABY, a township, joint with Keverstone, in the parish of STAINDROP, south-western division of DARLINGTON ward, county palatine of DURHAM, 6 miles (N.E. by E.) from Barnard-Castle, containing 203 inhabitants. Raby castle, situated on an eminence commanding a vast prospect, is a noble and extensive pile, surrounded with ramparts and a deep fosse, enclosing an area of two acres; from its stately exterior, which retains most of its original appearance, . a good idea may be formed of the grandeur of a baronial mansion in ancient times; the style of the south front, with the elegant symmetry of its windows, have at once a pleasing and sublime effect; the interior has been much modernised, and comprises numerous convenient apartments, furnished with great elegance. A carriage-road now passes over the site of the great hall, or ancient place of rendezvous, which was a truly magnificent apartment, having two rows of octagonal piers and a beautiful groined roof.
