 Castles at the Latter Part of the Tzvelfth Centmy. 87 the burh of the English Morcar, where are the remains of a shell keep upon the mound. Here the mound is central between and common to both wards. The general enclosing curtain is tolerably perfect, and the whole affords an excellent example of the manner in which the Norman architects dealt with an earthwork when the mound stood in the centre of an enclosure, instead of as usual upon one side of it. On the edge of the Honour of Pickering is Hamlake or Helmsley, the seat of the Barons de Ros before they inherited Belvoir, and where the remains of a very late rectangular keep stand on one side of a rectangular court, having two regular gate- houses, walls built against lofty banks, and beyond them strong and extensive outworks in earth and masonry. It is difficult to form an opinion upon the age of these earthworks. They impinge upon and are certainly later than a small Roman camp. At Mulgrave and Normanby were castles ; at the latter are still parts of a rectangular Norman keep. Mul- grave stands on the sea cliff. It was the seat of the Saxon Wada and afterwards the Castle of Nigel Fossard and the Mowbrays. At Gilling somiC early vaults and walls are worked into the later castle of the Fairfaxes. Thirsk, Black Bourton in Lonsdale, and Malzeard, the " capita " of three Mowbray Baronies, all contained castles of some importance in the twelfth century. Of Malzeard and Bourton the earth- works are considerable. Tadcaster, a place of strength both in Roman and Danish times, possessed also a Norman castle, of which, however, only the mounds remain ; and there is even less of Hugh Puiset^s work of Northallerton, surrendered to Henry II. in 1 1 74, and ordered to be destroyed in 11 77. Its earthworks are intersected by a railway. Of Tanfield, a Fitz-Hugh and Marmion castle, there are still some small remains. The great castle of North Yorkshire is Richmond, so called by Earl Alan, who obtained in 1070 the possessions of the English Edwin, and removed the seat from the adjacent Gilling, where the earthworks long remained, to a stronger position on the Swale. The Norman Castle was built in 1071 : it includes a large area, most part of which is defended by a natural cliff. The containing wall is mostly original, and within its substance is a curious small Norman chapel. The rectangular keep is placed at the weakest part of the circuit next to the town, and in front of it are the remains of a bar- bican. The well-known " Registrum Honoris de Richmond " specifies to which part of the castle the castle guard of each great tenant w^as due, and the Hall which the family of Scolland were bound to maintain and guard to this day bears
