Although the various parts of the celebrated hall have been built at widely different periods, and upon a sloping and irregular rocky platform, its plan is very easy to understand, and it may be well, at the outset, to explain the disposition of the buildings as clearly as may be. They surround two courtyards--the lower one, to the west, on the river front, and the upper one, separated from the first by the great hall and domestic offices, rising up to the east on the hill-side behind it. The visitor enters the lower quadrangle at its north-western angle, placing his foot, as he passes the postern, in a hole which has been worn deeply by unnumbered strangers before him. He notices, on his right, beneath the archway, the porter’s room, with a bedstead that may well have kept that functionary wakeful; and beyond it, still on the right hand and western side, the so-called Chaplain’s Room--with its hunting-horn, old musket, Seventeenth Century boots, service of pewter platters, and other miscellaneous contents--as well as two other chambers, before the domestic chapel is reached. This edifice occupies the south-western angle, and extends about half-way up the southern side of the lower courtyard. Being not at right angles with the other portions of this quadrangle, it gives, with its picturesque bell-turret, a pleasing variety to the buildings within; and, externally, its east window and the angles of its chancel and southern aisle, with the heavy buttress at the western end, add materially to the picturesque effect of the hall. The chapel, moreover, contains, with some of the foundation walls, the oldest portions of the edifice, and the round column and chalice-like font are anterior, perhaps, to the coming of the Vernons to Haddon. The south side of the western quadrangle is completed by a range of constructions, including passages to the private apartments, and a turret stair to the battlemented wall; and leading up to the doorway is a flight of steps--added in the Sixteenth Century--which projects into the area of the courtyard. This space is further broken up by the three steps which extend across it from north to south, dividing it into an upper and a lower platform. Standing upon the slight elevation thus gained, the chapel, the buildings opposite on the western side, the entrance gateway, with the very curious corbelling and constructive ties over it in the angle, and the offices on the western side, with the turret, have a most pleasing and varied effect.
