The building is perhaps modeled after SemperOper of Dresden, however it is supposed to be double as beautiful as the Yerevan building is two sided: One side (entrance from the Theatrical/Freedom square) is home to Opera and Ballet Theatre, while the street side houses the Khachaturian Concert Hall. For music fans, attend cheap and excellent performances at the Opera or the Chamber Music Orchestra. If a national dance group is performing, don’t miss it.
