Dominique Perrault Architecture's new Paris Longchamp Racecourse to open Sunday

Designed like a set of "transparent ‘shelves’”, the horizontal structure creates generous perspectives of the racecourse landscape. Spectators will be able to view the entire racecourse whether they are on the terraces, walkways, or open staircases.

The four-level structure comprises about 10,000 seats, a restaurant, a rooftop terrace, five reception rooms, five bars, a brasserie, and separate facilities for the press and hospitality. The first two levels are open to the public, the third floor is reserved for jockeys and owners, and the fourth and fifth floors are designated VIP areas. All the levels are slightly offset from each other, with the last level overhanging by about 20 meters.

The former buildings that housed support services for the races were demolished and rebuilt as pavilions, and four existing historic buildings were renovated, including: the administrative pavilion, the horse stables (which were extended), the offices in the 1920s-era “Totalizer” building; and the restoration of the 1921 Pavilion tribune originally built by architect Charles Adda.
