The Gloucester Old Bank was a British bank that operated between 1716 and 1838. It was founded in 1716 by James Wood. The bank was said to have been the oldest private bank in Britain, having survived the financial consequences of the Napoleonic Wars when many other banks went out of business. The claim is wrong as both C. Hoare & Co. and Child & Co. were founded earlier; the Gloucester Old Bank was, however, one of the oldest banks in Britain in the nineteenth century.
