Inverted relative to the sketchbook’s foliation, the subject is continued on folio 69 recto opposite (D02570). Twizel Castle, above the road bridge at Cornhill upon Tweed, is a Gothick folly, built around the core of a medieval fortalice in the 1770s by Sir Francis Blake. It is some four miles south–west of Norham. The structure remained intact until the early years of the twentieth century, but is now a ruin.
