Change Alley, London

Exchange Alley or Change Alley is a narrow alleyway connecting shops and coffeehouses in an old neighbourhood of the City of London. It served as a convenient shortcut from the Royal Exchange on Cornhill to the Post Office on Lombard Street and remains as one of a number of alleys linking the two streets. Shops once located in Exchange Alley included ship chandlers, makers of navigation instruments such as telescopes, and goldsmiths from Lombardy in Italy.

The coffeehouses of Exchange Alley, especially Jonathan's and Garraway's, became an early venue for the lively trading of shares and commodities. These activities were the progenitor of the modern . Similarly, Lloyd's Coffee House, at No. 16 Lombard Street but originally on Tower Street, was the forerunner of Lloyd's of London, the Lloyd's Register and Lloyd's List. See English coffeehouses in the 17th and 18th centuries for more on their importance.

The nearest London Underground station is Bank and the closest mainline railway station is Cannon Street.

Lombard Street and Change Alley had been the open-air meeting place of London's mercantile community before Thomas Gresham founded the Royal Exchange in 1565. In 1698, John Castaing began publishing the prices of stocks and commodities in Jonathan's Coffeehouse, providing the first evidence of systematic exchange of securities in London. Many , who had been expelled from the Royal Exchange for their rude manners, also migrated to Jonathan's and Garraway's.
