statue of Louis XV was removed during the French Revolution, and the obelisk, statues and fountains were added in the 19th century. Ecole Militaire Louis XV decided in 1751 to create the Ecole Militaire, the first French military academy, to train five hundred young men from poor noble families "gentlemen" in the art of warfare. The site chosen was next to the plain of Grenelle, on the left bank to the west of the city center.

The facades of the Petit Trianon represented in its most pure form the emerging style of Neoclassicism in France. Royal Opera of Versailles Much of his attention was devoted to modifications of the Palace of Versailles desired by Louis XV.

Gabriel made a new proposal for the same sit in 1748, but it was also put on hold due to the cost. occupied himself with numerous modifications to the exterior of the Palace, notably the completion and extension of the North Wing, following closely the original
