Die Verbindungen von der Kapelle zur Reggia, die Juvarra nicht vollendete, wurden unter Carlo Emanuele III. von Benedetto Alfieri ausgeführt, dem auch die eindrucksvolle Monumentaltreppe zur Empore zu verdanken ist. ###>The architectural passages from the Church to the Reggia were not finished by Juvarra, but were completed by Benedetto Alfieri under Carlo Emanuele III. Alfieri also designed the monumental staircase leading up to the tribune of the Church.
