CBA is a benchmark space for many event-planning companies, as they find the perfect stage to make their ideas come true inside its premises. It is a 15,000 square meter building with four exhibition halls, a workshop area, six multipurpose rooms, a games and billiards room, a theatre, two historic halls –Salón de Baile (ball-room) and Sala de Columnas (columns room)–, a cinema, a radio station, a bookshop and a large restaurant known as "La Pecera" (the fishtank). Its perfect location –it is found right at the centre of Madrid–, its outstanding rooms, full of history and with a very personal flavour, make it the best choice for any kind of event.
