The Palace of Versailles Research Centre (in French: "Centre de recherche du château de Versailles" - CRCV) is the first research centre established in a French palace.
 It originated as part of a French government project called "Digital Great Versailles" (in French, "Grand Versailles Numérique") to improve public access to the Palace of Versailles.
 It is located in the Jussieu pavilion, near the Grand Trianon and the Petit Trianon, on the grounds of the Palace of Versailles, which is in the Île-de-France region of France.
Mary Madeline "May" Bonfils Stanton (April 30, 1883 – March 11, 1962) was an American heiress and philanthropist.
 She and her younger sister, Helen Bonfils, succeeded their father, Frederick Gilmer Bonfils, as principal owners of "The Denver Post".
 However, May's elopement at age 21 with a non-Catholic salesman had forged a rift in her relationship with her parents and sister that worsened when Helen inherited the lion's share of their parents' estates.
 Following a three-year legal battle over the inheritance, the sisters cut off all communication with each other.
 May married twice but did not have children.
 Living a reclusive life, she invested her fortune into building and furnishing her 750 acre estate in Lakewood, Colorado – which included a mansion that was an exact replica of Marie Antoinette's Petit Trianon château in Versailles – and into many philanthropic endeavors in the state of Colorado.
 The Bonfils–Stanton Foundation, established by her second husband after her death in 1962, continues to support the arts in Colorado.
 She was posthumously inducted into the Colorado Women's Hall of Fame in 1985.
Five subsidiary structures located near the Palace of Versailles have a historical relation with the history and evolution of the palace.
 Of these five structures – the Ménagerie, the Pavillon de la Lanterne the Trianon de Porcelaine, the Grand Trianon (also called the Marble Trianon), and the Petit Trianon – two have been destroyed (the Ménagerie and the Trianon de Porcelaine); however, historical documentation and accounts permit these two structures to be discussed.
 As an ensemble of buildings related to, yet removed from, the chateau of Versailles, they represent architectural masterworks of the 17th and 18th centuries that have inspired architects to this day.
The Hameau de la Reine (] , "The Queen's Hamlet") is a rustic retreat in the park of the Château de Versailles built for Marie Antoinette in 1783 near the Petit Trianon in Yvelines, France.
 It served as a private meeting place for the Queen and her closest friends, a place of leisure.
 Designed by the Queen's favoured architect, Richard Mique with the help of the painter Hubert Robert, it contained a meadowland with lakes and streams, a classical Temple of Love on an island with fragrant shrubs and flowers, an octagonal belvedere, with a neighbouring grotto and cascade.
 There are also various buildings in a rustic or vernacular style, inspired by Norman or Flemish design, situated around an irregular pond fed by a stream that turned a mill wheel.
 The building scheme included a farmhouse, (the farm was to produce milk and eggs for the queen), a dairy, a dovecote, a boudoir, a barn that burned down during the French Revolution, a mill and a tower in the form of a lighthouse.
 Each building is decorated with a garden, an orchard or a flower garden.
 The largest and most famous of these houses is the "Queen's House", connected to the Billiard house by a wooden gallery, at the center of the village.
 A working farm was close to the idyllic, fantasy-like setting of the Queen’s Hamlet.
Miss Morison's Ghosts is a 1981 British supernatural television drama broadcast by ITV starring Hannah Gordon and Wendy Hiller.
 It is based on a book by two Oxford academics, Charlotte Anne Moberly and Eleanor Jourdain who claimed that in 1901, on a day trip to Versailles, they travelled back in time to the 18th century court of Louis XVI of France, in an event known as the Moberly–Jourdain incident.
Richard Mique (] ) (18 September 1728 – 8 July 1794) was a neoclassical French architect born in Lorraine.
 He is most remembered for his picturesque hamlet, the "Hameau de la Reine" — not particularly characteristic of his working style — for Marie Antoinette in the "Petit Trianon" gardens within the estate of Palace of Versailles.
The temple de l'Amour is a garden folly of the Château de Versailles, and more specifically, in the Petit Trianon part of it.
The Moberly–Jourdain incident (also the Ghosts of Petit Trianon or Versailles, French: "les fantômes du Trianon" / "les fantômes de Versailles") is a claim of time travel and hauntings made by Charlotte Anne Moberly (1846–1937) and Eleanor Jourdain (1863–1924).
Charlotte Anne Elizabeth Moberly (1846–1937) was an English academic and writer.
 She was the daughter of George Moberly, and was made the first Principal of St Hugh's College, Oxford.
 She rose to fame following an incident where she came to believe that she had slipped back in time whilst visiting the Petit Trianon in Versailles with fellow academic Eleanor Jourdain.
