The Bolshoi Theatre (Bol'shoy Teatr, meaning Large, Great or Grand Theatre, also spelled Bolshoy) is a historic theatre in Moscow, Russia, designed by architect Joseph Bové, which holds performances of ballet and opera. The Bolshoi Ballet and Bolshoi Opera are amongst the oldest and most renowned ballet and opera companies in the world. The theatre is the parent company of The Bolshoi Ballet Academy, a world-leading school of ballet. The main building of the theatre, rebuilt and renovated several times during its history, is a landmark of Moscow and Russia (its iconic neoclassical facade is depicted on the Russian 100-ruble banknote). On 28 October 2011, the Bolshoi was re-opened after an extensive six year renovation costing about 21 billion rubles (about $680 million).The renovation included restoring acoustics to the original quality (which had been lost during the Soviet Era), as well as restoring the original Imperial decor of the Bolshoi.
