With the sketchbook inverted is a sketch of the entrance to Carlisle Castle at the south of the complex. The castle is shown in Turner’s watercolour of Carlisle circa 1832 (Yale Center for British Art, USA),1 for volume 1 of Scott’s Poetical Works, but from the opposite direction to this sketch. The sketches for that design are in the Minstrelsy of the Scottish Border sketchbook (Tate D25844; Turner Bequest CCLXVI 42 a).
The inscription has not been deciphered fully.
