The Castle is situated on very high ground, nearly in the center of the city; the principal entrance is by a handsome gateway. The several buildings, surrounding two squares, consist of the lord-lieutenant's state apartments, guardrooms, the offices of the chief secretary, the apartments of aides-du-camp and officers of the household, the offices of the treasury, hanaper, register, auditor-general, constabulary, etc., etc. The buildings have a dull and heavy character--no effort has been made at elegance or display--and however well calculated they may seem for business, the whole have more the aspect of a prison than a court. There is, indeed, one structure that contributes somewhat to redeem the somber appearance of "the Castle"--the chapel is a fine Gothic edifice, richly decorated both within and without. The following description of the ancient character of "the Castle" is gathered from Dr. Walsh: "The entrance from the city on the north side was by a drawbridge, placed between two strong round towers from Castle Street, the westward of which subsisted till the year 1766. A portcullis, armed with iron, between these towers, served as a second defense, in case the bridge should be surprised by an enemy. A high curtain extended from the western tower to Cork Tower, so called after the great Earl of Cork, who, in 1624, expended a considerable sum in rebuilding it. The wall was then continued of equal height until it joined Birmingham Tower, which was afterward used as a prison for state criminals; it was taken down in 1775, and the present building erected on the site, for preserving part of the ancient records of the kingdom. From this another high curtain extended to the Wardrobe Tower, which served as repository for the royal robe, the cap of maintenance, and the other furniture of state. From, this tower the wall was carried to the North or Storehouse Tower (now demolished) near Dame's Gate, and from thence it was continued to the eastern gateway tower, at the entrance of the castle. This fortress was originally encompassed with a broad and deep moat, which has long since been filled up. There were two sally ports in the wall, one toward Sheep (now Ship) Street, which was closed up in 1663 by the Duke of Ormond, after the discovery of Jephson and Blood's conspiracy." The walls by which it was formerly surrounded, and the fortifications for its defense, have nearly all vanished. Neither is Dublin rich in remains of antiquity; one of the few that appertain to its ancient history is a picturesque gateway, but not of a very remote date, called Marsh's Gate. It stands in Kevin Street, near the cathedral of St. Patrick, and is the entrance to a large court, now occupied by the horse police; at one end of which is the Barrack, formerly, we believe, the Deanery, and Marsh's library.
