The view is from the beach on the east side of Lulworth Cove, Dorset, the only point inside the cove from which the Isle of Portland is visible on the horizon to the south-west, through the seaward entrance. The drawing continues a little onto on folio 21 recto opposite (D08831). Presumably because the profile of Portland is disrupted through coinciding with the gutter between the two pages, Turner repeated this part of the view on folio 20 recto (D08829).
There is some brown spotting at the bottom right.
