In 1845 Turner made two last journeys to France. On the first short visit in May he returned to Boulogne, from where he explored the coast to the north: watercolours from that tour hang nearby in this room. In early September, his final trip to the Continent focused on Dieppe, Eu and Le Treport, during which he was continually on the look out for 'storms and shipwrecks'. This sketchbook was used on the later visit and contains many views of the castle and harbour at Dieppe. The study on this page represents a nocturnal effect, in which the moon is indistinctly seen through clouds above the sea.
