Employing agile line, here Turner has sketched a view of the town of Colchester in Essex. Colchester Castle is visible atop the ridge at centre and the River Colne and Middle Mill are rendered in the foreground. This sheet is related to the highly finished watercolour of Colchester produced for the England and Wales print series (Courtauld Institute Galleries, London).1
