This museum is dedicated to Anton Dvorak, the great Czech composer known for employing aspects of Czech folk music of Bohemia and Moravia into his compositions. The museum is on two floors. The lower floor mainly documents his life, while the upper floor does the same, but is mostly taken up with presentation of his music and operas. There's a listening post that plays many of his most famous compositions such as Symphony No. 9, the Czech Suite, plus much more that I wasn't familiar with.
The museum is great for fans and interesting even for non dedicated, but interested in classical music types.
