The true effect of this treatment is difficult to capture in a normal photograph. Perhaps you can see best by looking at the urn on the far wall - of course it's not a real ornament with a view behind through the window, but a marvellous trick of the eye. The stairwell has three arched apertures each containing trompe-l’oeil urns with flowers painted to actual size. The landscape "behind"in the paintings is a view of the South Downs in Sussex with painted horizon lining up visually with the actual horizon which can be seen through the windows on the other side of the stairwell.
