The House of Music is a sound museum in Vienna. It is a fun museum on rainy days. We wanted to visit the "Haus des Meeres" first but my husband wanted to hear some music, so we went to the "House of Music" instead. It is really a great museum and the kids loved it.
They learned all about classic music (Mozart and other austrian componists) and they really loved the sound machine. You can see, feel and even create the sounds and noises yourself.
We will visit this museum definitely again when we will be in Vienna next year!
