The Vienna State Opera, a Renaissance-style building, is a city of music and there are many opera houses in Vienna. The entire building was destroyed by fire in 1945 and later rebuilt, and has been the venue for the Vienna Opera Ball. At the door, there is also a waiter wearing a court costume holding a concert performance table and sipping a foreigner to pass the show. The opera house is very beautiful and luxurious, but it is a pity that I can't go inside. There are only staff members who can go in and can only check at the entrance.
