text: Stadiums After its foundation following the merging of Olympique Lillois and SC Fives, Lille alternately played its home games at the stadiums of both clubs: Stade Henri-Jooris of Olympique Lillois and Stade Jules-Lemaire of SC Fives. However, in 1949, the club chose to keep the first as his home ground and to use the second as a training ground. Becoming more and more obsolete, Stade Jules-Lemaire will be destroyed ten years later, in 1959. Named after Henri Jooris, the iconic president of Olympique Lillois, the 15,000-seat stadium, located by the Deûle river, near the Citadel of Lille, was the home of Les Dogues until 1975 when Lille moved at Stade Grimonprez-Jooris.
  Located inside the citadel park, not far from the former venue, the stadium's original capacity was 25,000 at the time it was opened, but this was reduced to around 17,000 by 2000 due to the evolution of safety standards. In 2000, the stadium was renovated and its capacity was increased to 21,000. However, it still failed to meet FIFA licensing regulations and plans to build a new stadium compliant with UEFA's standards were made in 2002, when the club was privatized.
  In June 2003, the club's board agreed to a new proposal put forward by the city mayor to build a new 33,000-seat stadium on the site of the Stade Grimonprez-Jooris. Preliminary works which included dismantling of training grounds were undertaken, and the delivery was scheduled for 31 December 2004 but was postponed. Construction work was then planned to begin in early 2005, but the project faced opposition from preservationists who successfully prevented the project to obtain necessary permits as the site of the stadium was close to the 17th-century citadel.
