The gate-house, or north wing, of this manor-house was greatly altered in 1282, but within its upper chamber can be seen the ends of the old corbels embedded in the wall, and the line of the original wall-top much below that of the thirteenth century. Similar broken-off corbels can be seen in the two upper rooms in the north part of the west wing, whilst the profile of the inner wall of the north wing can be clearly seen on the east face of the gate-house. The south end of the west wing of the manor-house is plainly visible with its coign stones forming a vertical line in the middle of the present west wing of the castle, as seen from the outer courtyard, and a corresponding line of junction can be observed in the upper part of the outer wall of the same wing facing the moat. In the end or south wall of this wing of the old manor-house (now merely a partition wall between two rooms of the lengthened thirteenth century wing) there remains a blocked-up slit-window, which I hope presently to open again. All but one of the windows of this manor-house were replaced by larger openings in 

Wyatt’s days. The only original window is that on the ground floor facing south beside the entrance archway. There are several original arrow-slits. some of them very  small with no place for the knuckles of the archer. One larger arrow-slit facing west was half cut away in the fourteenth or fifteenth century and a trefoil-headed window inserted. Some of the arrow-slits of this period in the north wall were built up by Wyatt.
   Another fact about the twelfth-century manor-house worth mention is the immense thickness (some 2 feet) and relatively marked slope of its flat roof, as shewn by the offsets that outline it above and below on the gate-house wall. It must have been made of rammed clay carried on timbers supported by the great corbels I have mentioned. The Penchester additions, a century later, were roofed with lead, of which the cut-off strip remains built into the wall in one place.
   Another partly remaining feature of this manor-house is the enclosure or garden-wall. This started from the south
