The slope to the right of the castle in the main drawing is followed down to the sea in a continuation in the bottom left corner. This is a more detailed treatment of one of the views on folio 220 verso opposite (D08760; CXXIII 217a).
Eric Shanes has noted this detailed drawing of the castle as a source for the watercolour Pendennis Castle, Cornwall, Scene after a Wreck of about 1816 (private collection),1 engraved in 1817 for the Picturesque Views on the Southern Coast of England2 (see the concordance of the series in the 1811 tour introduction), although Turner followed the main lines of a partially coloured drawing of the castle in its wider coastal setting in the larger Ivy Bridge to Penzance sketchbook (Tate D08905; Turner Bequest CXXV 27), which probably provided enough information in itself.
For other views in and around Falmouth see under folio 7 verso (D08375).
