The portico, one of the finest of its kind, is ninety-six feet wide, and seventy-four feet high. That of St. Martin's Church is only sixty-four wide, and the Post Office seventy-six. The whole building was rapidly completed. The foundation-stone was laid by Prince Albert, January 17th, 1842, John Pirie, Esq., being Lord Mayor. A huge red-striped pavilion had been raised for the ceremonial, and the Duke of Wellington and all the members of the Peel Cabinet were present. A bottle full of gold, silver, and copper coins was placed in a hollow of the huge stone, and the following inscription (in Latin), written by the Bishop of London, and engraved on a zinc plate:—

Sir Thomas Gresham, Knight,
Erected at his own charge
A Building and Colonnade
For the convenience of those Persons
Who, in this renowned Mart,
Might carry on the Commerce of the World;
Adding thereto, for the relief of Indigence,
And for the advancement of Literature and Science,
An Almshouse and a College of Lecturers;
The City of London aiding him;
Queen Elizabeth favouring the design,
And, when the work was complete,
Opening it in person, with a solemn Procession.
Having been reduced to ashes,
Together with almost the entire City,
By a calamitous and widely-spreading Conflagration,
They were Rebuilt in a more splendid form
By the City of London
And the ancient Company of Mercers,
King Charles the Second commencing the building
On the 23rd October, A.D. 1667;
And when they had been again destroyed by Fire,
On the 10th January, A.D. 1838,
The same Bodies, undertaking the work,
Determined to restore them, at their own cost,
On an enlarged and more ornamental Plan,
The munificence of Parliament providing the means
Of extending the Site,
And of widening the Approaches and Crooked Streets
In every direction,
In order that there might at length arise,
Under the auspices of Queen Victoria,
Built a third time from the ground,
An Exchange
Worthy of this great Nation and City,
And suited to the vastness of a Commerce
Extended to the circumference
Of the habitable Globe.
His Royal Highness
Prince Albert of Saxe-Coburg and Gotha,
Consort of Her Sacred Majesty,
Laid the First Stone
On the 17th January, 1842,
In the Mayoralty of the Right Hon. John Pirie.
Architect, William Tite, F.R.S.
May God our Preserver
Ward off destruction
From this Building,
And from the whole City.

At the sale of the salvage, the porter's large hand-bell, rung daily before closing the 'Change (with the handle burnt), fetched £3 3s.; City griffins, £30 and £35 the pair; busts of Queen Elizabeth, £10 15s. and £18 the pair; figures of Europe, Asia, Africa, and America, £110; the statue of Anne, £10 5s.; George II., £9 5s.; George III. and Elizabeth, £11 15s. each; Charles II., £9; and the sixteen other royal statues similar sums. The copper-gilt grasshopper vane was reserved.

The present Royal Exchange was opened by Queen Victoria on October 28, 1844. The procession walked round the ambulatory, the Queen especially admiring Lang's (of Munich) encaustic paintings, and proceeded to Lloyd's Reading-room, which was fitted up as a throne-room. Prince Albert, the Duke of Wellington, Sir Robert Peel, Lord John Russell, Sir Robert Sale, and other celebrities, were present. There the City address was read. After a sumptuous déjeuner in the Underwriters' room, the Queen went to the quadrangle, and there repeated the formula, "It is my royal will and pleasure that this building be hereafter called 'The Royal Exchange.'" The mayor, the Right Hon. William Magnay, was afterwards made a baronet, in commemoration of the day.

A curious fact connected with the second Exchange should not be omitted. On the 16th of September, 1787, a deserted child was found on the stone steps of the Royal Exchange that led from Cornhill to Lloyd's Coffee-house. The then churchwarden, Mr. Samuel Birch, the well-known confectioner, had the child taken care of and respectably brought up. He was named Gresham, and christened Michael, after the patron saint of the parish in which he was found. The lad grew up shrewd and industrious, eventually became rich, and established the celebrated Gresham Hotel in Sackville Street, Dublin. About 1836 he sold the hotel for £30,000, and retired to his estate, Raheny Park, near Dublin. He was a most liberal and benevolent man, and took an especial interest in the Irish orphan societies.

The tower at the east end of the Exchange is 177 feet to the top of the vane. The inner area of the building is 170 feet by 112, of which 111 feet by 53 are open to the sky.

The south front is one unbroken line of pilasters, with rusticated arches on the ground floor for shops and entrances, the three middle spaces being simple recesses. Over these are richly-decorated windows, and above the cornice there are a balustrade and attic. On the north side the centre projects, and the pilasters are fewer. The arches on the ground floor are rusticated, and there are two niches. In one of them stands a statue of Sir Hugh Myddelton, who brought the New River to London in 1614; and another of Sir Richard Whittington, by Carew. Whittington was, it must be remembered, a Mercer, and the Exchange is specially connected with the Mercers' Company.

On the east front of the tower is a niche where a statue of Gresham, by Behnes, keeps watch and ward. The vane is Gresham's former grasshopper, saved from the fire. It is eleven feet long. The various parts of the Exchange are divided by party walls and brick arches of such great strength as to be almost fire-proof—a compartment system which confines any fire that should break out into a small and restricted area.

West of the Exchange stands Chantrey's bronze equestrian statue of the Duke of Wellington. It was Chantrey's last work; and he died before it was completed. The sculptor received £9,000 for this figure; and the French cannon from which it was cast, and valued at £1,500, were given by Government for the purpose. The inauguration took place on the anniversary of the battle of Waterloo, 1844, the King of Saxony being present.

On the frieze of the portico is inscribed, "Anno XIII. Elizabethæ R. Conditvm; Anno VIII. Victoria R. Restavratvm." Over the central doorway are the royal arms, by Carew. The keystone has the merchant's mark of Gresham, and the keystones of the side arches the arms of the merchant adventurers of his day, and the staple of Calais. North and south of the portico, and in the attic, are the City sword and mace, with the date of Queen Elizabeth's reign and 1844, and in the lower panels mantles bearing the initials of Queen Elizabeth and Queen Victoria respectively. The imperial crown is twelve inches in relief, and seven feet high. The tympanum of the pediment of the portico is filled with sculpture, by Richard Westmacott, R.A., consisting of seventeen figures carved in limestone, nearly all entire and detached. The centre figure, ten feet high, is Commerce, with her mural crown, upon two dolphins and a shell. She holds the charter of the Exchange. On her right is a group of three British merchants—as Lord Mayor, Alderman, and Common Councilman—a Hindoo, a Mohammedan, a Greek bearing a jar, and a Turkish merchant. On the left are two British merchants and a Persian, a Chinese, a Levant sailor, a negro, a British sailor, and a supercargo. The opposite angles are filled with anchors, jars, packages, &c. Upon the pedestal of Commerce is this inscription, selected by Prince Albert: "The Earth is the Lord's, and the fulness thereof."—Psalm xxiv. I. The ascent to the portico is by thirteen granite steps. It was discussed at the time whether a figure of Gresham himself should not have been substituted for that of Commerce; but perhaps the abstract figure is more suitable for a composition which is, after all, essentially allegorical.
