Mrs. Fitzherbert’s mansion, now the residence of W. Furner, Esq., the Judge of the County Court of this district, adjoining the present mansion of Captain Thellusson, was built in 1804. On the site now occupied by the square block of buildings that form the north-east corner of Castle Square, about forty years since, stood the Castle Tavern, which had been one of the chief rendezvous of royalty, the nobility, and the gentry. It was originally a very small house, but being considered the best in the town for a tavern, it was purchased by Mr. Shergold, who opened it under the sign of the Castle, in 1755. Such was its success, in consequence of the increase of visitors to the town, that, in 1776, Messrs. Tilt and Best joined him in partnership, and the premises were greatly extended. In 1790, the other parties having given up the business, Mr. Tilt carried on the undertaking, and he was succeeded by his widow. In 1814, Messrs. Gilburd and Harryett became the proprietors. It attained the acme of its celebrity when in the hands of Mr. Tilt, who attached to the establishment an elegant suite of Assembly and Concert Rooms, built with great taste and judgment by Mr. Crunden, of Park Street, London, in 1776. The Ball Room was rectangular, 80 feet by 40 feet, with recesses at each end and side, 16 feet by 4 feet, decorated with columns corresponding with the pilasters which were continued round the room, dividing the sides and ends into a variety of compartments, ornamented with paintings from the Admirander and the Vatican, representing a portion of the story of Cupid and Psyche, and the Aldrobrandini marriage; with air-nymphs and divers other figures, in the ancient grotesque style. The ceiling was curved, and formed an arch of one fifth of the height of the room, which was 35 feet. Over the entablature, at each end of the room, was a large painting; the one a representation of Aurora, and the other a figure of Nox. In 1814, a beautifully toned organ by Flight and Robson was erected at the north end of the room.
