According to Mr. Wilkins, the entrance into the Barbican was at the south end of Golden-Ball-Lane, and not at the north, as Blomfield has it; over each foss in this direction was a bridge, but only one of them remains; this extends across the inner ditch, and according to Mr. Wilkins, is formed of “the largest and most perfect arch of Saxon workmanship in the kingdom.” This bridge is nearly 150 feet in extent, and the Castle stands just across it on the south west part of the hill; the extent of the Castle from east to west, including a small tower through which was the principal entrance, is 110 feet 3 inches, and from north to south, 92 feet 10 inches; and the height to the top of the battlements, 69 feet 6 inches; the height of the basement story is about 24 feet, which is faced with rough flint; the upper part is ornamented with small arches and decorated so as to appear something like Mosaic work; the small tower before-mentioned on the east side, was of a richer kind of architecture, called, Bigod’s Tower, which is now chiefly inclosed, defaced or pulled down, as in the year 1793 the county thought it necessary to erect a new goal, and it was resolved to attach it to the eastern side of the old Castle. Mr. Wilkins expresses himself justly indignant at the addition, which he calls an heterogeneous and discordant mass.—This venerable pile has been a castle of defence to British, Saxon, and Norman kings; it has been the boast and pride of the province for ages past, yet by this recent change it is bereaved of its ancient beauty; but, surely, whatever alterations were necessary, they might have preserved the same character and apparent date of architecture with the mutilated parts of this stately pile. The interior is also now an unroofed area, although formerly covered and divided by floors. The entrance to the top of the Castle is on the west side, at the south corner by a flight of 99 steps. The Castle precinct contains upwards of six acres, and the summit of the hill is in circumference 360 yards, the whole of which is enclosed with iron palisadoes, as is also the ditch around it; which, within the last 20 years, have been occupied for gardens, many of which are tastefully laid out; and the summit of the hill on all sides commands a most delightful view of the city and surrounding country. The Castle with the hill and ditch surrounding it, may be considered a _chef d’œuvre_, and the prospect therefrom superior to any thing of the kind in England. A panoramic view of the city and surrounding country has been lately published by Messrs. Stevenson, Matchett, and Stevenson, taken from several stations on the hill. The shirehouse which joins the Castle, has lately undergone complete internal repair, and considerable alteration whereby the courts are enlarged and rendered much more commodious than heretofore; and here all county business is transacted, and the summer assizes held.
