A comparison of this sketch with the drawing in folio 28 verso (D25977; CCLXVII 28a) suggests that this is Innerwick Castle. A photograph of the castle from the south-west in the archive of the Royal Commission on the Ancient and Historical Monuments of Scotland also matches this sketch quite closely.1
There is a similar view but from further away on folio 53 of this sketchbook (D26017; CCLXVII 53). For more information on the castle see folio 28 verso.
