A competition was held in 1894 for the general layout of the  Exposition Universelle, for which some 100 projects were considered. The  first-prize winner was Eugène Hénard, for whose project the Palace of  Industry (constructed for an international exposition in 1855) was to be  demolished to make way for a grand exhibition hall (the Grand Palais), a  smaller exhibition building (the Petit Palais), and a bridge (Pont  Alexandre III). A new street (present-day Avenue Winston-Churchill)  connecting the Champs-Élysées to the bridge also was subsequently built.  In 1896 a second competition was held for the actual design of the  Grand Palais, and this time the award was granted jointly to the four  top architects. Henri Deglane, Albert Louvet, and Albert Thomas were  each assigned a different portion of the building to design, while the  whole project was overseen by Charles Girault. The intention was to link  the Grand Palais, the Petit Palais, and the Pont Alexandre III to the  Champs-Élysées and to the Hôtel des Invalides across the Seine.

The Grand Palais’s stone facades, columns, and friezes exhibit  features of Classical design, while the intricate metalwork inside is in  the style of classic Art Nouveau.  The building is composed of three major areas: the Galeries Nationales,  the Palais de la Découverte, and the Nave. The area known as the Nave  is an iron-and-steel structure with stone walls, and it is crowned by  elegant glass vaults. The Nave’s glass roof constitutes the largest such  structure in Europe, reaching a height of 45 metres (150 feet) under  its dome and spanning some 200 metres (650 feet) in length. At the heart  of the Nave is the Great Staircase. Altogether, the three sections of the Grand Palais cover 72,000  square metres (775,000 square feet).
The Grand Palais is currently the largest existing ironwork and glass structure in the world, a title once held by London's  Crystal Palace, which was lost in a fire. This palace with the Belle  Epoque-style pinnacle boasts 9,400 tons of steel framework, 15,000 sq.  meter (162,000 sq ft) of glass, and about 5,000 square meter (5,400 sq  ft) of galvanized iron/zinc roofing. The exterior is made of stone and  features beautiful colored mosaics and intricately sculpted statues. 
Dedicated “to the glory of French art,” the Grand Palais was  intended to showcase the fine arts and France’s leadership in that  realm, but it hosts a wide variety of cultural events: from concerts,  automobile shows, and fashion shows to fencing tournaments. The Galeries  Nationales host major art exhibitions; the Palais de la Découverte,  located in the building’s west wing, holds an interactive science  museum; and the Nave is the setting for a wide variety of cultural and  social events. A restaurant-lounge (the Mini-Palais) is located between  the building’s Nave and massive colonnades, and its terrace offers a  sweeping view of the surroundings. Located in the south wing of the  Grand Palais is CAPE (the Centre d’Accueil de la Presse Étrangère), a  press centre for foreign journalists stationed in Paris and a popular  setting for press conferences, formal meetings, and public debates.

After one of the Grand Palais' glass ceiling  tiles  fell in 1993, the building was closed for more than a decade for  renovations. The first portion reopened in 2004, the remainder in 2007.  Renovations included repair of the metal framework, replacement of the  glass, and the repairing and recovering of the roof. The  mosaics were also completely repaired and restored.
