Until 15 September 2018, all parts of the stadium contained seating. However, most supporters in the Marek, being a side stand, used to keep standing during the games as it is considered the kop and are considered as the most fervent supporters in the stadium, which makes the stadium different from most of the other stadiums, as the most fervent fans tend to usually sit behind the nets. Since 15 September 2018, the Marek contains a standing area again, as well as the lower parts of the Trannin and Delacourt stands since the start of the 2022–2023 season. The stadium's capacity is now 38,223.Official RC Lens web site . rclens.fr.
