Fontaine du Trocadéro, Water fountain in Jardins du Trocadéro, Paris, France

Fontaine du Trocadéro is a rectangular basin topped by a series of symmetrical smaller basins operating in a closed circuit, set in the Trocadéro Gardens below the Palais de Chaillot. Twenty angled water cannons, fifty-six jets and twelve water columns propel 5,700 litres per second. Two freestanding sculptures, The Joy of Life by Léon-Ernest Drivier and Youth by Pierre-Marie Poisson, flank it near the Seine.

The present fountain replaced a cascade built by Gabriel Davioud for the 1878 Universal Exposition, which carried bronze mascarons by Auguste Rodin and was demolished in 1935. The new fountain was built for the 1937 International Exposition, when the old Trocadéro Palace gave way to the Palais de Chaillot. Architects Roger-Henri Expert, Paul Maître and Adolphe Thiers designed it; Daniel-Joseph Bacqué and Léon-Ernest Drivier were the sculptors.

The fountain is also called the Warsaw Fountain, after the Place de Varsovie that borders its lawns. Its water cannons are aimed toward the Eiffel Tower, and in 1989 Mireille Mathieu sang La Marseillaise here with the French Army Choir, broadcast live on television.

The fountain sits in a rectangular basin below the Palais de Chaillot, reached by metro lines 6 and 9 at Trocadéro station. Its footprint, lawns and basins together, is bounded by the place de Varsovie, avenue Albert-Ier-de-Monaco, avenue Hussein-Ier-de-Jordanie and avenue Gustave-V-de-Suède. The water cannons fire toward the Eiffel Tower, so the display is seen from the Chaillot side.

In 1989, for the Eiffel Tower's centenary and the French Revolution's bicentenary, Mireille Mathieu sang La Marseillaise with the French Army Choir in front of the fountain, broadcast live on French television. The fountain also appears in Laurent Voulzy's 1977 music video for Rockollection.
