The well-stair, which lies between the tower and its north curtain, at a height of about 10 feet, leads by a narrow branch to a niche or recess in the curtain, having a drop-arch, reinforced by a plain chamfered rib. This recess is open in the rear, and has a loop raking the outside of the tower and the cross-wall of the outer ward. The stair goes on to the first and second floor and leads. The first floor, also a pentagon, has on the south face a good but plain early Decorated stone chimney hood, with scroll moulding and plain corbels. In the two eastern faces are loops. In the west is a large two-light window, a modern restoration, and close to it a lancet opening, no doubt once a door leading to the south curtain. The staircase door enters on the north side, and close to it is a loop pointing north along the face of the curtain. From this floor a passage leads along the curtain towards the Broad Arrow Tower; from it opens a small garderobe. There is a third stage, and above it the battlements. Salt Tower was the meeting point of four curtains. These were the east and south walls of the inner ward, of equal height and thickness, and two walls of smaller dimensions, of which one ran east, and traversed the east member of the outer ward, and one ran south to Well Tower, and traversed the south member. Each of these had a gateway, opening into the space between them, and leading to the Iron Gate postern. Of the five loops on the ground-floor of Salt Tower, two opened north-eastward upon the outer ward, two south-westward upon that ward towards Cradle Tower, and one south-eastwards towards Galleyman Tower and the postern. Salt Tower has undergone recent and complete restoration. Its original features, however, seem to have been preserved. A section of the curtain between Salt and Lanthorn Tower seen against the wall of the former show it to have been 10 feet thick and about 20 feet high, but the rest of it was probably removed before 1532 to make way for the Queen’s Gallery. This curtain terminated in the Lanthorn Tower. [Illustration: SALT TOWER.—FIRST FLOOR.] The Lanthorn Tower has been long since pulled down, but its foundation has lately been discovered. It formed a part of the palace, and contained the king’s bedchamber and private closet. It was circular, and probably originally of the age, size, and fashion of Wakefield Tower. As in 1532 it was called the New Tower, it may have been rebuilt in that or the preceding century. It was injured by fire in 1788 and pulled down, with a contiguous gateway which traversed the outer ward at this point. Lanthorn Tower is stated in the survey of 1532 to have been 106 feet distant from Wakefield Tower. The actual distance occupied by Lanthorn Tower and its curtains, that is from Salt to Wakefield Tower, was 343 feet.
