Drawn over two pages (continuing on folio 23; D13622; CLXVII 22) this view of Dunbar Castle from the west is very similar in composition and style to the drawing on folios 18 verso–19 (D13615–D13616; CLXVII 17a–18). Again, the sketch is dominated by a large rock in the foreground, beyond which at the right of the page can be seen the far end of the promontory of rock that houses the castle ruins. The drawing on this page is rather slight, using only a faint, though careful, pencil outline. There is more detail on the continuing page, which shows the castle.
There is light foxing across the page and a small brown mark at the bottom left.
