If you fancy finding a quiet corner in the very heart of the city, literally a few steps away from the noise of piazza Castello and the shopping-oriented via Po, via Roma and via Garibaldi, there is a little gem waiting for you.
Go to the north-eastern corner of the Piazza Castello arcades and you will find a small passage just beside the ticket office of the Teatro Regio. This gate will introduce you to the magical quiet of piazzetta Carlo Mollino, named after the architect that re-built the Teatro Regio in 1973 after a huge fire in 1936 completely destroyed it.
This little square looks like magic to me because it puts some space between you and the rest of the city, letting you “spy” on it as if you were behind the curtain in the near theatre. Even if just to place a quiet phone call, or to take a “backstage” picture of the buildings, just walk down the passage and look up: you will find only the strange and beautiful sky of Turin to limit your view. Do it in a day with blue sky patched with white clouds and you will never forget the framing of this nice picture.
The little square leads you to via Verdi if you cross it entirely and turn right down an almost hidden passage to come back to the real world.
