The Trocadéro gardens occupy a dramatic open space on the hillside across the Seine from the Eiffel Tower. The fountains and pools were designed by Roger-Henri Expert for the 1937 Exposition Internationale des Arts et Techniques dans la Vie Moderne (International Exposition of Arts and Technology in Modern Life) as was the Palais de Chaillot, which borders the gardens. The palace was the original headquarters of NATO and where the UN General Assembly adopted the Universal Declaration of Human Rights on December 10, 1948. Today it houses the Museum of Man (ethnology), the Naval Museum and the National Theater of Chaillot, one of the city's largest concert halls and where haut couture shows often take place.
