[1] The church was conceived in 1814, after the defeat of Napoleon, to celebrate the return to the throne of King Victor Emmanuel I of Sardinia from the Savoia family, after a 16 years long exile.

The necessity to plan out the spaces, which were recently employed by the fortification and the idea to build a votive temple, have to be seen as a unitary project.

Flanking the entrance staircase, atop two high plinths, are two statues representing Faith (with calyx) and Religion by Carlo Chelli.

The tympanum of the church states: ORDO POPVLVSQVE TAVRINVS OB ADVENTVM REGIS, which can be translated as: The Nobility and the People of Turin for the Return of the King.

[4] In front of the church is a statue of a King Vittorio Emanuele I, walking forward, holding a staff in his right arm, the base reads Vittorio Emanuele I/ Re di Sardegna/ Restituito a su Pepolo/il XX Maggio MDCCCXIV/ Ne Coronara/ la Fedeltà secolare.
