From its construction (1826–1830) the arch stood in a nearby location, slightly to the east, directly across from Burton's Ionic screen entrance to Hyde Park; it was moved a short distance to its current site at the top of the Constitution Hill road in 1882–1883.
The triumphal arch originally supported a colossal equestrian statue of the 1st Duke of Wellington by the sculptor Matthew Cotes Wyatt, acquiring its name as a result.
During the second half of the 1820s, the Commissioners of Woods and Forests and the King resolved that Hyde Park, and the area around it, should be renovated to match the splendour of rival European capital cities, and that the essence of the new arrangement would be a triumphal approach to the recently completed Buckingham Palace.
[3] There were no authoritative precedents for such buildings, which required windows and chimney stacks, in the classical style, and, in the opinion of architectural historian Guy Williams, "Burton's reticent treatment of the supernumerary features" and of the cast iron gates and railings was "greatly admired".
[6] Burton created a new design, "to pander to the majestic ego",[6] which was much larger and modelled on a fragment found in the Roman Forum, which was accepted on 14 January 1826, and subsequently built as the present Wellington Arch.
A contemporary account, written in anticipation of its completion to its original plan, describes what was intended:The entablature is lofty and elegant with a richly sculptured frieze, and a row of boldly projecting lions' heads on the cymatium, marking the centres of columns and other sub-divisions of the order.
[7]The arch at Constitution Hill was left devoid of decorative sculpture as a result of the moratorium in 1828 on public building work, and, instead, despite the absolute objection of Burton, was mounted with a monumental equestrian statue of Arthur Wellesley, 1st Duke of Wellington by Matthew Cotes Wyatt, the son of the then recently deceased James Wyatt, who had been selected by statue's commissioner, and one of its few subsequent advocates, Sir Frederick Trench.
[8] The bronze by Matthew Cotes Wyatt, which eventually crowned the arch, was, at 40 tons (40.62 tonne) and 28 feet (8.53 m) high, the largest equestrian figure ever made.
[8] A writer in The Builder asked Lord Canning, the First Commissioner for Woods and Forests, to ban the project: We have learnt, and can state positively, that Mr. Burton has the strongest objection possible against placing the group in question on the archway... and that he is taking no part whatever in the alteration proposed to be made in the upper part of the structure to prepare it to receive the pedestal... Mr. Burton, through the mildness which characterizes him, has not expressed this opinion so loudly and so publicly as he ought to have done.... an opinion prevails very generally, that he is a party to the proceedings, and this has induced many to be silent who would otherwise have spoken...[8]The Prime Minister, Sir Robert Peel, contended that another site would be preferable, and proposed, on behalf of the Crown, to offer any other site, but the statue's subscribers rejected all alternative proposals.
The face of London might have been very different now – freer, perhaps, of the 'monstrous carbuncles' so disliked by the present Prince of Wales – if the attacked party [Decimus Burton] had been a little more pugnacious, and so better equipped to stand his ground".
[11] The campaign led by Fearon was successful: Wyatt's statue was removed to Aldershot, and its place on Burton's arch, which was moved to Constitution Hill in 1883,[2] was occupied by a Quadriga by Captain Adrian Jones.
[citation needed] The boundary of Buckingham Palace Garden was moved south, and a new road named Duke of Wellington Place was created; this separated the space containing the Arch from the rest of the Green Park.
