The Church of St. Peter ad Vincula, mentioned in the reign of John, and rebuilt in the late Perpendicular period, still occupies the north-west quarter of the ward. In the south-east quarter stood the Royal Palace, destroyed, at various times, by James, Cromwell, or after the Restoration. The keep in Norman castles was intended rather for the occasional than the regular residence of the lord, whose ordinary lodgings were more conveniently placed in the inner ward. This was so at Rochester, in 1281, at Bamborough, Carlisle Porchester, and elsewhere. Here the palace stood between the keep and the ward wall, and, besides, had walls of its own; one crossing from Wakefield Tower to the keep, where were drum-towers and a gateway known as Cold Harbour, and another called the Wardrobe Gallery, crossing from Broad Arrow Tower to the keep, and having upon it Wardrobe Tower, also circular, with a circular turret. The Queen’s Gallery extended from Salt to Lanthorn Tower, on the line of the curtain, and the great hall was connected with Wakefield Tower. The whole space was occupied by small courts and gardens, lodgings, and offices; and the buildings in the reign of Henry III. seem to have encroached upon the outer ward, where were two posterns for the service of the palace. These buildings, after the manner of royal houses, were always under repair; and seem to have absorbed much of the money expended on the Tower. The main guardhouse stands on the site of Cold Harbour. The foundation of the Queen’s Gallery and great hall have lately been laid open. Norman masonry, part of the ward-wall, has also been discovered. In the earlier surveys, the palace quarter is called the “Inner Ward.” Cold Harbour was probably very lofty; for, in 1572, complaint was made that Sir Owen Hopton, the lieutenant, allowed his prisoners to meet and walk on the “leads of Cold Harbour”; and about that time the Earl of Southampton stayed leaping upon the tower, his wife being on the opposite side of the ditch. Of the twelve mural towers of this ward one caps each of the five angles. Two were intermediate on the south face, as two still are upon the east, and two upon the north, one on each side of the salient. The west, or shortest face, has one large intermediate tower. The gatehouse, called the Bloody Tower, stands considerably west of the centre of the south front, and opposite to Traitor’s Gate. It is contiguous to Wakefield Tower, which flanks it on the east, and probably determined its position and that of Traitor’s Gate. Commencing with Wakefield, and passing westwards, the towers are, Bloody, Bell, Beauchamp, Devereux, Flint, Bowyer, Brick, St. Martin’s or Jewel, Constable’s, Broad-Arrow, Salt, and Lanthorn Tower, now destroyed.
