Ange-Jacques Gabriel was the principal architect of King Louis XV of France. His major works included the Place de la Concorde, the École Militaire, and the Petit Trianon and opera theater at the Palace of Versailles. His style was a careful balance between French Baroque architecture and French neoclassicism.

The Place de la Concorde is one of the major public squares in Paris, France. Measuring 7.6 ha in area, it is the largest square in the French capital. It is located in the city's eighth arrondissement, at the eastern end of the Champs-Élysées.
