Residents crossing Piazza Castello pass the windowless palace wall to work or study under Guarini's geometry, trading daylight for total silence in the dense core.

À propos du lieu

Guarino Guarini turned the royal church into an architectural puzzle of interlocking geometric ribs and hidden daylight.

Emmanuel Philibert founded the sanctuary after leading Habsburg forces to victory over French troops at Saint-Quentin on the feast of Saint Lawrence. That triumph restored Turin to ducal authority under the Treaty of Cateau-Cambrésis. The duke renovated the older chapel of Santa Maria ad Presepae near the entry. Standing beside the Royal Palace, the church established the house of Savoy in its recovered capital.

Guarino Guarini engineered the interior by altering classical rules inherited from Roman Baroque architects. The floor plan begins square, transitions into an octagon above the columns, and shifts into a Greek cross at the vaults. Above the circular base, intersecting ribs form an open lattice recalling Spanish Islamic vaults. Behind a curved archway, the high altar receives daylight directed downward from a concealed cupola.
