The town was walled round by Richard Fitz-Alan, who had a licence for that work in 1295. There were two gates, one below and on the river, the other called St. Mary’s, at the top of the town. The town wall seems to have abutted upon the castle, which thus formed a part of its defence. The present duke has built just outside the castle, and not far from the parish church, a large church dedicated to San Filippo Neri, a very noble structure, and fitted up with great simplicity and excellent taste. Unfortunately, it is so placed as to detract materially from the general aspect of the castle from the plain below. Placed a little lower down, it would have left the castle as the predominant figure, permitted the fine old parish church to hold its due place, and have supported and elevated, instead of somewhat oppressing, the whole group. THE CASTLE OF BARNARD CASTLE. Barnard, or Bernard’s, Castle, so called from its founder, Bernard de Baliol, stands in a commanding position on the left bank of the Tees, here the boundary between Durham and Yorkshire. It is a large castle, and was long a very important one, both from its position on the frontier of the bishopric, and from the power of the great barons who built and maintained it. The castle crowns the summit of a steep and in part precipitous shelf of rock, which rises about 100 feet above the river, and has a projecting shoulder, by means of which the north-western quarter of the fortress is protected naturally by a cliff. The remainder of the area was covered by a deep and broad artificial ditch, now mostly filled up, which intervened between the east and north sides of the castle and the contiguous town, to which it gave name, and the people of which, in the times when the castle was maintained, looked to its lords for protection. The north front of both town and castle received a further defence from the Percy beck, a stream which flows into the Tees about 450 yards higher up. The area of the castle, within the walls, is rather above 8 acres. In plan it is oblong, having four unequal sides, averaging about 293 yards north and south by 133 yards east and west. The east or town side, the longest, is slightly convex, and measures 336 yards; the west, or that upon the river, 245 yards; the north end, 160 yards; and the south end, 110 yards. The Tees Bridge springs from the rocky bank, below the centre of the western front, and was commanded from the battlements.
