Organized by Construiracier, an association that promotes the use of this material in construction and architecture, the Eiffel Trophies aim to showcase architectural works created in whole or in part using steel.

The material steel had already enabled the racecourse to receive a distinction in 2019 at the European Steel Design Awards. 

Inaugurated in 2018, the Paris Longchamp racecourse stands out in the landscape, on the edge of the Bois de Boulogne, with its new large grandstand, built in place of old grandstands dating from the 1960s. The new grandstand, whose levels are slightly inclined towards the track and offset from each other up to the last overhanging level, evokes the idea of a galloping horse.

The steel material proved to be particularly relevant to provide the transparency, flexibility and lightness required by the project. The large, more compact and functional grandstand (180 m x 35 m) has a seating capacity of around 10,000 on four levels, a restaurant, a large rooftop terrace, five reception rooms and a brasserie. The third floor is reserved for jockeys and owners, while the fourth and fifth floors host VIP areas.
