In the space between the two ranges, it was proposed to erect a fountain, formed of the eight column's of the portico of Carlton House, (which was in elaborate imitation of the Temple of Jupiter Stator, at Rome,[1]) to which eight on the same model were to be added. The balustraded terrace had been continued fronting the Park with a view to this embellishment. It however occurred to some guardian of the public weal, that the above space presented an eligible opportunity for a grand public entrance from Pall Mall into the Park. The idea was mooted in Parliament; but some difficulties arose, from the leases already granted to the builders of the houses on the terrace, who had calculated on the _exclusive_ appropriation of the latter. The anxiety of the public for the improvement at length reached the present King; and it was the first popular act of his patriotic reign to command a grand triumphal[2] entrance to be formed, with all possible speed; the difficulties being then easily removed. The necessary portion of the terrace was accordingly removed, and the magnificent approach formed, as shown in the Engraving. While these improvements were in progress, a monumental memorial had been projected by the British Army to their late commander-in-chief, the Duke of York; an expression of grateful sympathy which must be recorded to the honour of truly British hearts. The funds for this tribute were augmented by each individual of the above branch of the service contributing one day's pay. The design was furnished by Mr. Benjamin Wyatt, the architect of the superb mansion built for the Duke of York; and, after the execution was somewhat advanced, it was resolved to set up the tribute in the place it now occupies. The monument consists of a plain Doric column, surmounted with a colossal statue of the Duke of York. The pedestal and shaft are of fine granite. The plinth, or base of the pedestal, is 22 feet square, and the pedestal 18 feet; the circumference of the shaft is 11 feet 6 inches, decreasing to 10 feet 2 inches at the top; the abacus is 13 feet 6 inches square. The interior of the column may be ascended by a winding staircase of 169 steps, lit by narrow loop-holes. From the top stair a doorway opens to the exterior of the abacus, which will be enclosed with a massive iron railing, so as to form a prospect gallery. The iron-work is not yet completed; but, as we have enjoyed the view from two sides of the square, we can vouch for its commanding a fine _coup d'oeil_ of the whole metropolis, and certainly the finest view of its most embellished quarter. From this spot alone can the magnificence of Regent-street be duly appreciated, and above all the skill of the architect in effecting the junction of the lines by the classical introduction of the Quadrant.
