The Trocadéro, site of the Palais de Chaillot, is an area of Paris, France, across the Seine from the Eiffel Tower. The hill of the Trocadéro is the hill of Chaillot, a former village. The place was named in honor of the Battle of Trocadero, in which the fortified Isla del Trocadero, in southern Spain, was captured by French forces led by the Duc d'Angoulême, son of the future king, Charles X, on August 31, 1823.
