It is of modern design and offers a multi-sports hall for both schools and associations. It is topped with bleachers that can accommodate about a hundred people, also allowing for the organization of handball matches and boxing galas.
In 2011, it was dedicated to Léon Brouste, mayor of Morcenx from 1936 to 1977, in recognition of his commitment to the town's sporting life. Hence the numerous files overflowing from his briefcase in the mural depicting him. On this occasion, the entire gymnasium and sports hall complex was renamed the Léon Brouste Sports Complex.
Equipped with annexes (three double changing rooms and a first-aid room), it also houses a reception hall, the CAM basketball and handball hall, and the CAM tennis and badminton clubhouse. Volleyball, badminton, and basketball courts, as well as three tennis courts, have been developed around the gymnasium. Tennis tournaments are held there, including tournaments for athletes with disabilities. This modern gymnasium will be complemented by what will become the Distillery Sports Hall.
To meet the growing demand for sports facilities from schools and associations, a multi-sports hall was started in the spring of 2024.
