One reason for the popularity of picturesque views in this period was an awareness that traditional areas of Britain were being developed and modernised and therefore changing irrevocably. Many views captured in engraved form no longer existed later in the nineteenth century. By 1822 the medieval castle
of Chester had been demolished and a neo-classical construction, designed by the architect Thomas Harrison, had been erected in its place. Turner seems to have managed to sketch the ruins of the old castle before they were swept away.
