Opened in 1932, the complex is located southwest of Casablanca, in the Oasis neighborhood, about 24 km away from Mohammed V International Airport.

After the dissolution of USM in 1957 and the liquidation of its assets, Raja gained the right to use the Complex thanks to Abdelkader Jalal [fr] and Boujemaâ Kadri, then Secretary-general of the club.

The following year, the training centre underwent improvements, and a new synthetic turf was added during an opening ceremony on 11 November 2010 with the Minister of Youth and Sports, Moncef Belkhayat, Mohamed Aouzal [fr] and Abdessalam Hanat, then president of the club.

But after years of neglect, the development centre will close during the 2013–14 season and it is finally Andaloussi who will once again take charge of its renovation which began in 2018 under the newly elected president, Jawad Ziyat [fr].

The centre has been expanded to reach the capacity of 54 beds and the sports infrastructure dedicated to young footballers were developed.

[9] After its opening in September 2022, Raja CA Academy began to host some youth teams in association with the Oasis complex.

This education was provided by the Office for Skills Training and the Promotion of Work [fr] (OFPPT) thanks to a partnership with the club.

[11] In 2018, several agreements were signed with specialized establishments to ensure a quality school and sports project for the young athletes.

[13] After the opening of the development centre in 1999, the management was given to experienced coaches who were former Raja players like Fathi Jamal, Mhamed Fakhir or Mohamed Madih, in charge of physical preparation.

[15] The club annually allocates a budget of approximately 4 millions dirhams to the training centre, in order to provide for all the needs necessary for these players, supervised by a technical and administrative staff.
