Turner seems to have considered Dunstanburgh as the subject matter of a large watercolour on which he was working about 1800 which eventually became a view of Pembroke Castle, exhibited at the Royal Academy in 1801 (National Museum Wales, Cardiff)1 and again in a new, slightly modified version, in 1806 (Art Gallery of Ontario, Toronto);2 see under folio 1 recto (D03994). The anchor in the left foreground and boat to the right occur in that study.
The artist had already made views in both oil and watercolour of Dunstanburgh from the sea; see Tate D00890, D00891, D01112 and D01113 (Turner Bequest XXXIII S, T, XXXVI R, S). Note also the drawings of Dunstanburgh in the Wilson sketchbook (Tate D01211–D01212; Turner Bequest XXXVII 94–95), and in the Dynevor Castle sketchbook (Tate D01603–D01604; Turner Bequest XL 82a–83).
