This view has only recently been identified as showing Laufenburg, on the Rhine. In it Turner reworks a subject he had observed more than forty years earlier, on his very first tour of the Continent.
This work is typical of a handful of the watercolours he painted during his 1844 tour, in the unusually restrained, almost monochromatic treatment of the subject. Forms are invoked rather than stated,
as the eye attempts to bring them into focus. In this it resembles the great painting Norham Castle, Sunrise, which was also painted around this time (on display downstairs in room C1).
