Vienna Opera Ball And welcome to the show from here in the German capital. The Vienna Opera Ball is one of the highlights of the season for Austrian society and takes place in the Vienna State Opera house which is turned into a ballroom for the night. Normally it's a very traditional event but this year it's been given a bit of a makeover. There's a new organiser and also the theme of the ball is rather unusual for such an event. To celebrate co-hosting the European championships later this year the focus is on football.
