De 1895 à 1940
The Société d’Encouragement become the owner of the racecourse.
Construction of a rail spur and a railway station close to the racecourse, which today is the Sévigné roundabout and the parking area for horseboxes. It is inaugurated on 16 March and is only dismantled in 1942 by the Germans.
1898 which saw the creation of the training centre upon the signature of tolerance leases between the park association and twelve trainers so that the so-called round sand tracks, as well as the straight (the Jacques Laffitte track), could in future be used for training racehorses.
These leases were quickly transformed into individual agreements and into a convention to regulate the circulation of horses within the park.
Inauguration of a new racecourse built by André Raimbert. The architect adopts the neo-regionalist Normandy style, from the stands to the most simple pavilions in the center of the infield: half-timbered combinations, overhanging eaves and thick timber bracing, etc…
The parent company buys several areas within the park to the border of the Mesnil Le Roi, where it wants to build more stables. Horses are trained on forest tracks of that era: La Muette and Chaillou, as well as on the Achère grass track. During the year, the company continues to grow and builds new installations for jump horses (Rond Adam, Rond de l’Epine) and for flat horses (Rond Poniatowski, Rond Boileau).
The war puts a stop to horseracing in the provinces.
