The École Militaire/Unesco district is in the prestigious area between the Trocadéro and Avenue de Breteuil, famous for its gardens. The École Militaire is an 18th century architectural masterpiece. The castle and the courtyard still bear historical scars, like the mark left by a bullet in the mirror of the Salon des Maréchaux. The building also hides a chapel, concealed inside the castle itself, a library, and a bust room.
