For years, the Auditorium of the Plana de l’Om in Manresa was home to the Caixa Manresa Foundation, carrying out social and cultural initiatives for the local community in a centrally located, very busy setting, one of the city's main venues to promote culture, as well as the site of a wide range of activities by organisations, associations and groups of different kinds. The facility has an exhibition hall and an auditorium, a multi-purpose area where conferences and other activities can be held in the city.
Starting in 1998, Grup Transversal was responsible for the educational service related to the different exhibitions, some of which it also produced. Similarly, in 2005 it also took over the management of this venue and became co-responsible for its promotion.
The management of this site included visitor services; managing activities; creating and running workshops and educational activities, mainly aimed at schools; security and visitor services in the exhibition hall; and support for communication.
