Theater Metro Station

Teatralnaya is an underground metro station on the Zamoskvoretskaya line of the Moscow Metro, named for the nearby Teatralnaya Square, the location of numerous theaters, including the famed Bolshoi Theatre. The station is unique in that it does not have its own entrance halls. The north escalator leads to Okhotniy Ryad and the south escalator to Ploshchad Revolyutsii.
