Brough, Brougham and Appleby, Carlisle and Newcastle, Helmsley, Scarborough, and Richmond, all Norman rectangular keeps of the Northern Counties, are parts only, though the chief part, each of its castle, and it is only to fortresses so composed of parts that it is usual to apply the name of castle, a single structure being usually termed a tower or peel. Bowes, however, is always styled a castle in the records, and it is, of course, possible that it may, in respect of composition, have resembled other castles, and that the stronger and better-built part of the work may have proved most durable. It is, however, clear that no other work in masonry abutted upon, or, at least, was bonded into this tower, nor is there any indication of building or of foundations in the greensward, to which the tower on two of its sides lies open. On another side the churchyard runs up to within but a few feet of the tower, and on the remaining side the cottages show nothing of either old walls, or of the material of which such were likely to have been constructed. Bowes Keep, if then Keep it may be called, is a rectangular tower rather above 82 feet east and west by 60 feet north and south. It does not, however, stand with the main points of the compass, the actual north being the north-west angle of the description. It is about 50 feet high. Each angle is capped by a broad flat pilaster, 14 feet broad and projecting a foot, and the angle of meeting of each pair is solid. Midway, in the centre of each face, is also a pilaster 8 feet 10 inches broad, and of the same projection with those flanking it. There is no base or plinth or set-off, save where a plain string-course marks the level of the upper floor, and is continued along the whole building, walls and pilasters. The top of the wall is much broken down, no battlement remaining. There do not appear to have been turrets at the angles, save perhaps one at the south-east, containing the stair head. There is a basement, a main, and an upper floor. The basement, as usual, is at the ground-level. Its walls are 11 feet to 12 feet thick and solid, enclosing an area 36 feet by 58 feet. This again is subdivided by two cross-walls, 4 feet 4 inches thick. One of these, lying north and south, seems to have ascended through each floor, the other at right angles to it was probably confined to the basement. Both walls are broken away, only enough being left to show that such there were. Of the three chambers thus formed, that occupying the west end of the floor was 37 feet long by 16 feet broad (_a_). Of the two others the southern was 37 feet 10 inches long by 17 feet broad (_c_), and the northern the same length by 15 feet broad (_b_). [Illustration: BOWES CASTLE. FIRST OR MAIN FLOOR.
