The tower that presides over the harbour scene with shipping at the centre of this page is one of Guernsey’s distinctive eighteenth-century ‘loophole’ towers, built to defend the island against the French invasion.1
Inverted in relation to the sketchbook as foliated, the faint sketch of coastal rocks on the top half of the page follows the outline of the rock formations around Creux Harbour on the neighbouring island of Sark. This tiny bay constitutes one of the volume’s major preoccupations; for a list of these drawings, see the entry for folio 58 recto (D23629; Turner Bequest CCLII 58).
