This multidisciplinary space was designed to bring together a wide range of artistic events, whether music, visual arts, theatre, dance, literature, cinema or architecture.

It includes exhibition and conference rooms, a cinema and a concert hall, which serves as home to the Belgian National Orchestra (BNO).

[5] The building was originally intended to be built of stone, but Horta made a new plan of reinforced concrete with a steel frame.

It took more than a decade to complete the complex, which contains a large concert hall—the Henry Le Bœuf Hall—in an unusual ovoid, or egg shape.

Up to ten exhibitions a year are organised at BOZAR, and have included Jeff Wall, Luc Tuymans, Frida Kahlo, Lucas Cranach, Gilbert & George, Wim Delvoye, Venetian, Flemish Masters, Keith Haring and "It's not only rock'n'roll Baby".
