Cour d'honneur in the context of "Courtyard"

Hôtel particulier (French: [otɛl paʁtikylje] ) is the French term for a grand urban mansion, comparable to a British townhouse. Whereas an ordinary maison (house) was built as part of a row, sharing party walls with the houses on either side and directly fronting on a street, an hôtel particulier was often free-standing and, by the 18th century, would always be located entre cour et jardin – between the cour d'honneur (an entrance court) and the garden behind. There are hôtels particuliers in many large cities in France.

In architecture, a corps de logis (French pronunciation: [kɔʁ də lɔʒi]) is the principal or main block, or central building of a mansion, country or manor house, castle, or palace. It contains the rooms of principal business, the state apartments and the ceremonial or formal entry.

The grandest and finest rooms within the corps de logis are often found not at grade level, but on the first or even the second floor above. This floor is often referred to as the Italian piano nobile, the French bel étage, or the German beletage.

The Marble Arch is a 19th-century white marble-faced triumphal arch in London, England. The structure was designed by John Nash in 1827 as the state entrance to the cour d'honneur of Buckingham Palace; it stood near the site of what is today the three-bayed, central projection of the palace containing the well-known balcony. In 1851, on the initiative of architect and urban planner Decimus Burton, a one-time pupil of John Nash, the arch was relocated to its current site, near the northeast corner of Hyde Park, so that expansion of Buckingham Palace could proceed.
