The identification of this rather wobbly drawing as Brough Castle is based on its proximity to several views of Fox Tower in Helbeck near Brough in Cumbria (see folio 34; D25589). Turner passed both structures as he travelled between Appleby and Barnard Castle, and as Gerald Wilkinson has pointed out, the sketch has the appearance of being made from a moving coach.1
This view of the castle with the keep at the right of the picture, and indeed all the others, were evidently made from the north, and therefore from the road. Finberg’s identification of this sketch as a ‘Ruined castle on a rock’ is slightly misleading as the medieval castle in fact stands on what was originally an originally Roman earthwork. There are further sketches of the castle on folios 33 verso, 34 verso, 35, 37, 37 verso and 38 (D25588, D25590, D25591, D25595, D25596). Folio 37 is the most similar to the present sketch.
