The Bolshoi Theatre — one of the world’s biggest and most spectacular theatres — is known in all four comers of the world as the home of the outstanding Bolshoi Opera and Ballet companies.


Located near Red Square in Moscow, the Bolshoi Theatre was built in 1824. Over 2,000 people can sit inside this magnificent theatre on red velvet seats, underneath elaborate lights and beautiful gold decorations. It is simply impossible not to be amazed by a visit to the incredible Bolshoi Theatre — and that’s before a performance has even begun!


During its long history, the theatre has seen performances by some of Russia’s most famous artists and by some of the world’s best-loved composers. It has also survived some tough moments: three fires, the construction of the Moscow metro line underneath it and bombing during the war.


In 2005, engineers announced that the Bolshoi Theatre was extremely unstable and that it could fall down at any time. So that same summer, the theatre was closed and repair work began at great cost Currently, the reconstruction of the Bolshoi Theatre is expected to be completed around 2011.


When the theatre reopens, several things will have changed. But one thing won’t which is the theatre’s appearance. Every step is being taken to make absolutely certain that this magnificent theatre, when it reopens, will look exactly as it always did.
