Entre cour et jardin

Cour d'honneur (French pronunciation: ​[kuʁ dɔnœʁ], court of honor) is the architectural term for a three-sided ceremonial courtyard, created by flanking the main central block, or corps de logis, with symmetrical advancing secondary wings containing minor rooms. The Palace of Versailles (illustration) and Blenheim Palace (plan) both feature such entrance courts.

Some 16th-century symmetrical Western European country houses built on U-shaped groundplans resulted in a sheltered central door in a main range that was embraced between projecting wings, but the formalized cour d'honneur is first found in the great palaces and mansions of 17th-century Europe, where it forms the principal approach and ceremonial entrance to the building. Its open courtyard is presented like the classical permanent theatre set of a proscenium stage, such as the built Roman set of opposed palazzi in a perspective street at Palladio's Teatro Olimpico (Vicenza, 1584). Like the theatre set the built environment is defined and enclosed from the more public space by ornate wrought iron gilded railings. A later development replaced the railings with an open architectural columnar screen, as at Palais Royal (Paris), Schönbrunn Palace (Vienna), Charlottenburg Palace (Berlin), Alexander Palace (Saint Petersburg), or Henry Holland's Ionic screen formerly at Carlton House, London (illustrated below).

Technically, the term cour d'honneur can be used of any large building whether public or residential, ancient or modern, which has a symmetrical courtyard set apart in this way, at which the honored visitor arrives. (The rest may arrive without flourish, through a side entrance.)
