The ‘castle’ noted by Finberg is the old windmill at Clifton, refurbished in the 1820s as an observatory and camera obscura by the Bristol School artist William West,1 seen to the east above the Avon Gorge from Nightingale Valley in Leigh Woods. Brunel’s Clifton Suspension Bridge now springs from the point on the skyline below the small spot of foxing described in the Technical notes below, and the skyline is wooded, but the distinctive diagonal strata of the cliff are still recognisable from the opposite bank and from the bridge itself.
Two watercolours of about 1819 by Francis Danby also show St Vincent’s Rocks from Nightingale Valley (private collection and Bristol City Museum and Art Gallery respectively).2 The first, with a steep, open slope on the right and its screen of trees, may be from almost exactly Turner’s viewpoint, while the second seems to be from further back and higher up the valley.
