Jardins du Trocadéro was created in 1937 for an international exposition in Paris. The main feature, called the Fountain of Warsaw, is a long basin, or water mirror, with twelve fountain creating columns of water 12 metres high; twenty four smaller fountains four metres high; and ten arches of water. At one end, facing the Seine, are twenty powerful water cannon, able to project a jet of water fifty metres. Above the long basin are two smaller basins, linked with the lower basin by cascades flanked by 32 sprays of water four meters high. (Wikipedia)
