The view is north-westwards down through the woods to the shimmering River Medina and Cowes on its far bank, from the top of the steps from the path along the terrace outside the smaller of East Cowes Castle’s two conservatories; see for example the view including its façade and the steps from the opposite direction (Tate D20838; Turner Bequest CCXXVII a 35). The view over Cowes is comparable to those in various studies showing the castle in the distance from the south-east; see under D20804 (CCXXVII a 1). Another study with a prominent urn is D20816 (CCXXVII a 13).
This is among dozens of blue paper studies made in and around East Cowes Castle, presumably during the same visit. For more on the various aspects of the house (demolished in about 1950), and its lost grounds as depicted by Turner, see the Introduction to this subsection.
