 198 Mediceval Military Aixhitecture. the chalk, and at a high level, were no doubt always dry. Earl Roger, probably, found along the crest of these earthbanks the same sort of defences that he left behind him, on similar banks and mounds, at his paternal castle in Normandy ; but whether these were of timber or of masonry is uncertain. They might very well have been of either. It is, however, certain that the earl, or his immediate successors, inclosed the main area within a curtain of masonry, which ran up the mound and placed half of it, as at Lincoln and Tonbridge, outside the inclosure. Upon this curtain, a little south of the mound, was placed the gatehouse, and along it at various points were mural towers, probably square, of which one, on the curtain north of the mound, and known as Bevis Tower, still remains, though more or less altered. The domestic buildings were then, as now, along the sides of the lower ward, and upon the mound was placed a shell keep. As the public are only permitted to inspect the lower part of the gatehouse, the adjacent curtain, and the interior of the keep, it is impossible to form a correct opinion as to the extent of the original earthworks, or as to the age of the general curtain, or the basement of the domestic buildings, parts of which are said to be of Norman date. That the earthworks were extensive, and in part remain, may be seen from the summit of the keep, and from the upper gate of the park. Dallaway gives a large, but not quite correct, plan of the keep and its mound, the gatehouse and Bevis Tower, and the lower ward ; but his plan does not include the higher ward nor the earth- works, nor is it accompanied by any sections. Dallaway and Tierney were not strong in architectural details. The Gatehouse 'iX-^iXid.'i on the line of the curtain, projecting inwards from it, and upon the southern edge or counterscarp of the ditch of the mound. It opens into the lower ward. It is of the early Norman type, resembling that at Tickhill. It is a square of 32 feet, having in the outer and inner faces a large round-headed doorway, quite plain, without even a chamfer, and with a plain sloped abacus. The chamber is, of course, square, and but little broader than the door- ways. That towards the w^ard seems to have been closed by a pair of doors only. The other or outer doorway has a broad portcullis groove, which may or may not be original ; more probably not. The covering — the floor of the upper room — was no doubt of timber^ and flat. The present vaulting is an insertion. There was always an upper floor, but this has been much altered, chiefly in the Decorated period. The old loops, now blocked, may be traced. Some of the inserted windows are very late. In the south part of the inner doorway was a door opening into a mural stair leading to the upj^er floor and to the rampart-walk of the curtain, which seems to have been continued through the gatehouse, over the outer portal. The present staircase is exterior, and modern. This is the whole of the original gate- house, which, with the adjacent and very thick curtain, is probably the work of Earl Roger. The gatehouse has been extended outwardly in the Decorated
