The endowment of the City with a Bourse is generally attributed to the perception by Sir Thomas Gresham of the need for such a place of meeting,[8] though the matter had been mooted and the opinion of merchants taken thirty years before.

In the year 1537, Sir Richard Gresham, the father of Sir Thomas Gresham, whose business had taken him to Antwerp, when he saw the Bourse frequented daily by merchants, wrote a letter to Cromwell in which he suggested the erection of a Bourse in Lombard Street, as the place most frequented by merchants. As nothing came of the proposal he wrote again in the following year with an estimate of the cost, viz. £2000. If, he said, the Lord Privy Seal would induce Alderman Sir George Monoux to part with certain property at cost price he, Gresham, would undertake to raise £1000 towards the building before he went out of office. Whereupon the King addressed a letter to Monoux desiring him to dispose of certain property in Lombard Street, which was wanted for the commonweal of the merchants. Monoux, with Gresham’s consent, referred the matter to arbitration. A yearly sum of twenty marks to be paid by the City was offered. Monoux at first refused to take it, but afterwards, at the King’s request, consented. Then, for some unknown reason, nothing more was done. The matter was left over for many years.

At this time Thomas Gresham (son of Sir Richard by his first wife, Audrey, daughter of William Lynne of Southwick, Northampton) was nineteen years of age, and still serving his apprenticeship to his uncle, Sir John Gresham, Mercer. He was received into the Company in 1543. In the same year he was acting for the King at Antwerp. In 1551 he was appointed Royal Agent or King’s merchant, which caused him to reside at Antwerp during many months, and at frequent intervals. On the accession of Mary he was dismissed, but his services were speedily discovered to be necessary, and he was reappointed. Elizabeth continued his appointment.

In 1561 his factor, Richard Clough, wrote to him from Antwerp expressing his astonishment that London should have gone on so long without a Bourse:—

“Considering what a City London is; and that in so many years the same found not the means to make a Burse, but merchants must be contented to stand and walk in the rain, more like pedlars than Merchants. In this Country, said he (meaning Antwerp), and in all other, there is no kind of people that have occasion to meet but ye have a place for that purpose; indeed and if your business were done (here) and that I might have the leisure to go about it, and that I would be a means to Mr. Secretary to have his favour therein, I would not doubt but to make so fair a burse in London as the great burse is in Antwerp, without soliciting of any Man more than he shall be well disposed to give.”

Gresham remembered the attempt made by his father in 1538 and its failure; he resolved to take up the matter again, and in some way introduced it to the Court of Aldermen, who asked him, through one of their body, what he proposed to give himself towards the undertaking. This was in 1563, two years after Clough wrote his letter. Gresham took time to consider. In 1565 he sent in the offer. He would himself erect a “comely burse” if the City would provide a suitable site.

The site was found on the north side of Cornhill. Two alleys, Swan Alley and New St. Christopher’s, were purchased for £3532: the materials of the houses sold for £478. Subscriptions were invited and came in readily. On the 7th of June 1566 Sir Thomas was able to lay the foundation stone. Every one of the aldermen laid his stone or brick, with a piece of gold for the workmen.

The architect and the design came from Flanders. The Clerk of the Work, Henryk, was a Fleming, and most of the workmen were foreigners, special permission being granted for their employment. The City gave 100,000 bricks; the stone-work came from abroad, and “to this day” (Sharpe) “the Royal Exchange is paved with small blocks of Turkish hone-stones, believed to have been imported by Sir Thomas Gresham and to have been relaid after the fires of 1666 and 1838.”

Observe, therefore, that to the City belonged the site, but that the Exchange itself was the property of Gresham.

By the 22nd of December 1568 the Burse was so far complete as to allow of merchants meeting within its walls; but it was not till the 23rd of January 1571 that the Queen herself visited it in state, and gave it the name of the Royal Exchange. From the beginning a part of the Exchange was set aside for Marine Insurance, not a new thing, because it had long been the practice of the Lombard merchants in the thirteenth century to give such insurances.
