Pavillon Dufour, Royal entrance pavilion at Palace of Versailles, France

Pavillon Dufour is a pale-stone building on the left of the Cour d'honneur, its classical facade divided by pilasters and cornices and topped by a steep slate roof with dormer windows. The upper facade carries the inscription "A TOUTES LES GLOIRES DE LA FRANCE". It was built in 1818-1820 to plans studied by Alexandre Dufour, echoing Ange-Jacques Gabriel's wing, and its rear was never completed.

Napoleon I planned a white stone facade facing the town and ordered a study from Alexandre Dufour, who built the pavilion in 1818–1820 under Louis XVIII on the site of a 1668 wing. Its architecture copies the Gabriel wing built under Louis XV by Ange-Jacques Gabriel. The rear was never finished, and the 17th-century wing, restored in 1814, still stands behind it.

Since 2016 the first floor has held Alain Ducasse's 600 m² restaurant "Ore", named for the room's use under the monarchy, when courtiers gathered there. The name Dufour honours Alexandre Dufour, the architect Louis XVIII charged with building the pavilion from Napoleon's sketches.

The building is straightforward to locate as it sits directly at the entrance to the Palace of Versailles and serves as a clear landmark. Expect this area to be crowded during peak hours, so arriving early helps with a smoother visit.

The rear of the pavilion was never finished, although plans for it were sketched: the 17th-century wing was kept after its restoration in 1814 and still stands behind the 1818-1820 facade. The building's name honours Alexandre Dufour, the architect Louis XVIII entrusted with the work begun under Napoleon I.
