Elevation of the façade of the Hôtel du Roule

In 1768 Marquis de Marigny had Soufflot renovate his residence on faubourg du Roule. The architect designed a façade with Serlian archway in the centre, giving onto a loggia. Serlian archways were set on columns detached from the wall, creating two side openings that forma triptych with the main arch - the motif that characterizes Palladio's basilica in Vicenza. Construction was completed in 1771. Our knowledge of the project is based on four surviving drawings by Soufflot.
