472 Mediceval Military Architecture, This tower, being built against and not bonded into the keep, is evidently later, but resembles it in general style, and must have been added within a very few years. The explosion which shattered the keep has made evident the complete want of bond between the two buildings. East of the keep the ward is occupied by the remains of various offices, and by the ruins of the Queen's Hall or Tower. This, with its contiguous buildings, was constructed upon crypts, some of which remain. One is round-headed, with a pointed doorway ; another, which supported the Queen's Hall, seems to have had a very slightly pointed barrel-vault, divided by lateral narrower, but equally high, and therefore pointed, arches, into four bays, two of which contain lancet windows. Some of the hall windows remain. They are pointed, with drop arch recesses, and stone side seats. The tracery is gone, but the exterior labels remain, terminating in knobs of foliage, and the arris or angle of each recess is occupied by a scroll-bead moulding. North of this hall and placed across it, east and west, are the remains of what is regarded, with great probability, as the chapel. The west door and that of the hall are placed side by side, in a vestibule or porch, entered on the west side by a staircase. The doors are pointed, with half-round bead labels, and a scroU- bead moulding running round the jambs and arch. Inside, the chapel door is richer, and has in the arch a double scroll-bead, divided by a hollow, and for the jambs the hollow has been occu- pied by a detached column of Purbeck marble, which material, though much decayed, is still seen to have formed the base and bell capital. The design, though not highly ornate, is excellent, as is the execution. The whole of this group appears to be early English, of the latter part of the reign of Henry HI. Close to the east of the hall, between it and the curtain, is a depression, said to mark the well. This must have been of great depth — probably to the level of the brook. The tower spoken of as " La Gloriette " is probably gone, but near it is what may be called the Gloriette bastion, and what seems to be the angular base of a tower capping the south-east angle of the ward, and intended to cover the junction of the wall with the curtain which comes up from the Plukenet Tower. Near to it, westward, is a mural chamber in the curtain, which Treswell's plan shows as a garderobe, and beyond this an angular bastion, supposed to have been added by Lady Bankes, who seems to have placed a gun there. The great bastion is a very peculiar work. It is of rounded out- line, formed by a very thick and high wall of revetment, which caps the west end of the southern curtain, and projects into the middle ward. At the siege it carried five guns, and was called the New Bulwark. But, although it may then have been widened to carry a battery, it was probably only an addition to the older Norman
