Of Carlo Bossoli from Ada Peyrot, Vittorio Viale, Immagini di Torino nei secoli, Torino 1973
Moving from Piazza Castello or from the opposite Piazza Statuto, a baroque scenography is created thanks to the perspective telescope designed by the facades. This scenography was anticipated by the Theatrum Sabaudiae and realized by the court architects giving the city a sense of absolute power. Particularly Juvarra had already forseen, conceiving the Palazzo Madama facade, the perspective escape of the street that crosses the old town, centered on the backdrop with the Palace (hub of the entire urban structure).
