The old tradition of carnival balls continues to thrive in Vienna. Each year more than 450 balls take place, the higlight of the ball season is the Vienna Opera Ball held at the Vienna State Opera this very night. In 30 hours the opera has been transformed by 350 skilled workers and 150 auxiliaries into a gorgeous ballroom where more than 5.100 guests will spend a glittering ball night. This year's poster of the Vienna Opera Ball is a collage of "quotations" of different operas and milestones in the history of the ball.
