Louis XVI style completed the new Château de Compiègne (1751–83), begun by Louis XV, and decorated it from 1782 to 1786. The King's principal architectural addition to Versailles was the new library on the first floor (begun 1774). He was much more generous to Queen Marie-Antoinette; she redecorated the Grand Apartments of the Queen at Versailles in 1785, and carried out important works on her apartments at the Palace of Fontainebleau and Compiegne, as well as new apartments in the Tuileries Palace. The King also gave the Queen the Petit Trianon at Versailles, and in 1785 bought a new chateau for her at
Petit Trianon the 1760s and onward. Essentially an exercise on a cube, the Petit Trianon attracts interest by virtue of its four facades, each thoughtfully designed according to that part of the estate it would face. The Corinthian order predominates, with two freestanding and two engaged columns on the side of the formal French garden, and pilasters facing both the courtyard and the area once occupied by Louis XV's greenhouses. Overlooking the former botanical garden of the king, the remaining facade was left bare. The subtle use of steps compensates for the differences in level of the château's inclined location.
