The terrace of a luxurious apartment on the penthouse of an historical palace. Beyond the enclosure wall, treetops of the garden below. These fronds, wisely mixed with trees and shrubs planted along the perimeter, arranged in flower boxes realized according to the drawing, permit to deceive through an optical game resulting in the two views seeming one. The backdrop is made important by iron trellis that are covered by slabs of mirror, beyond which are hidden the technical rooms. The reflection and symmetry game show through an illusion the existence of a further garden beyond the wall and reveals glimpses through its sham arches carved in the drawing.
