It was built on today's Freedom Square, the former Royal Forum. The building has four concert halls, including the main hall with 1804 seats and three chamber halls for an audience of 250 to 450 people, as well as rehearsal rooms, conference and office rooms and exhibition space. The acoustic conditions of the main hall are adjusted individually to each repertoire - the acoustic chambers surrounding the hall and suspended ceilings lowered to an appropriate height allow the adjustment of the length of the sound.
