Probably an imaginary scene, the castle perhaps based on Llanstephan (Carmarthen) though there is no evidence that Turner travelled so far west in either 1792 or 1793. The invented subject, together with the signature on the verso (D40052), raises the possibility that this was a composition lent to a pupil for copying; compare Tate D00848 (XXXI F). If so, dating as it must from around 1792–3, this is the earliest recorded work of the type. For other drawings in this style, heavily influenced by P.J. de Loutherbourg (1740–1812), see Tate D00392 and D00396 (Turner Bequest XXIII R, V).
