Paris La Défense Arena, which stands at the foot of the Grande Arche, opened with a Rolling Stones concert that filled the 40,000-performance capacity stadium. The project was initiated and financed by Jacky Lorenzetti, President of Racing 92, who, following an architectural competition in 2010, chose Christian de Portzamparc and his team to design and build the stadium with Vinci.

Originally a rugby stadium and transformed into a performance venue at the design stage, with 31,000 sq.m of offices included in the architectural design, this building is one of a kind. Rising from the urban landscape between four streets on the major axis in La Défense and Nanterre, it is set against a backdrop of towers. The architect added a sheath of glass and aluminum scales to diffuse daylight under the drawn-out line of its high white concrete terraced seating in order to soften its exterior horizontal form. Its gentle outward appearance stands in stark contrast to the feeling of immensity on entering the stadium under its 40-metre-high vault.

As a sports stadium, the Paris La Défense Arena, home to the Racing 92 rugby team, has a seating capacity of 30,400. This makes it the largest closed performance arena in Europe and the second largest closed sports stadium in the world. The Paris La Défense Arena also has an original design – a fixed roof and mixed ground surface with synthetic turf that can be covered with slabs and transformed into a performance venue in eleven hours – and offers a high level of comfort and visibility and quality acoustics requiring exceptional fittings and equipment, a 1,400-sq.m giant screen and more. Composed of four giant girders, the roof rests on a very large span structure measuring 150 meters by 110 meters.

At night, the facade, sheathed in glass and aluminum scales, sends out infinite color variants into the surrounding urban area. As a performance venue, the Paris La Défense Arena, on the day of its inauguration, was the largest in Europe. It is also the second largest multi-sports arena in the world after the Philippine Arena.
