The chapel was inaugurated in 1692 to provide the “Pious Congregation of Bankers, Merchants, and Traders of Turin” (an association established in 1662) with a place for gathering and prayer. Its construction was made possible through the direct involvement of the rector of the Jesuits, Father Agostino Provana (1641-1726).
The interior consists of a rectangular hall covered by a vault frescoed by the painter Stefano Maria Legnani (known as Legnanino, 1661-1713) with themes centered on the “History of Salvation” drawn from the Old and New Testaments. The walls are adorned with twelve large paintings depicting scenes of the Glorification of the Epiphany, mostly the work of Andrea Pozzo and his workshop.
In 1769 the building was renovated by Bernardo Antonio Vittone, who designed the new façade.
In the sacristy, the altarpiece once on the altar of the original congregation chapel is preserved, depicting The Adoration of the Magi by Moncalvo, along with an ingenious universal mechanical calendar (from year 1 of the common era to 4000), constructed according to the design of the director of the Turin Astronomical Observatory Giovanni Amedeo Plana around 1835, decorated with a complex printed iconography.
