The buildings between the chapel and the south or garrison tower, to the upper part of which a passage, or covered-way, led along the top of the outer wall, are mostly in ruins. Here appear to have been the stables. The garrison tower adjoins the entrance to the keep; its foundation is a square of about thirty-six feet; but the three outward angles diminish as they ascend, and form triangular buttresses, so that the upper part of the tower is circular. The walls are at least eight feet in thickness. The entrances to this tower were so continued, that there was access to it from every part of the walls. It contained three floors, and in each of them a fire-hearth. The interior forms an irregular octagon, about twenty feet in diameter from the angles, and about seventeen from side to side. <g>Great Tower.</g>--The wall that extended between the keep and the west tower is in ruins. This tower, which is also greatly dilapidated, appears of more modern construction than the former, and is probably of the time of the Edwards. Its outward form is circular; but the interior is somewhat of an octangular figure, but very irregular, its general dimensions being thirty-three feet long, and twenty-five feet broad. In this appears to have been the great <g>kitchen</g>; the fireplace is still distinguishable, with a recess and loophole on each side. Here was a small doorway, or sally-port, communicating with a sort of outer _ballium_, which runs on the north-west side, and was enclosed by an outer wall. On this side also, and ranging between the west tower and the north or Ladies’ tower, were the state apartments. <g>The Hall</g> was a magnificent room of the time of Edward the First, as clearly appears from the style and architecture of its remains, and particularly from its long, slender, and narrow windows. This apartment was sixty-five feet long, and twenty-eight feet broad. Some years ago it contained a single beam of oak, “without knot or knarle,” sixty-six feet long, and nearly two feet square throughout its whole length. On the north-west side is the great fireplace; and behind it, projecting into the outer <g>ballium</g>, a vast mass of solid stonework, or buttress, which, in its upper part, appears to have had some little apartment, or guard-chamber. The hall communicated towards the north with a kind of withdrawing or retiring room, about twenty-nine feet by seventeen and a half, in which appears to have been a window looking into the hall. From this second apartment, a passage led into what seems to have been the great
