Little known to many visitors to the New Haven and Yale area, this museum is a wonderful treasure with displays of nearly 1,000 musical instruments and other artifacts. The museum is one of the largest and most important repositories of musical instruments in the world, and is especially known for its collection of clavichords, harpsichords and pianos. Located on historic Hillhouse Avenue (described by Mark Twain as "the most beautiful street in America"), this quiet museum is not to be missed.
