The Grand Trianon is a French Baroque style château situated in the northwestern part of the Domain of Versailles in Versailles, France. It was built at the request of Louis XIV of France as a retreat for himself and his maîtresse-en-titre of the time, the Marquise de Montespan, and as a place where he and invited guests could take light meals (collations) away from the strict etiquette of the royal court. The Grand Trianon is set within its own park, which includes the Petit Trianon.

Princess Marie of Orléans was a French princess, artist, and, by her marriage, duchess of Württemberg (1837). Before her marriage she was styled Mademoiselle de Valois.
