The Museum of Musical Instruments, or MIM as it's popularly known, is housed a former department store that was designed by the Art Nouveau architect Paul Saintenoy in 1899. With its curving black wrought-ironwork and huge windows, it's an impressive site. Just as impressive are the hundreds of instruments on display here, which are drawn from the museum’s vast collection of 7,000, the biggest in the world. The museum takes a chronological approach that goes from ancient Egypt to 19th-century experiments with mechanical instruments and on to our modern electric and electronic examples. The instruments make for a fascinating mix: bagpipes from Scotland; instruments made by Tibetan monks from the bones of colleagues; celebrity instruments like Django Reinhardt's guitar and ABBA's synthesizer; and odd saxophones that the instrument's creator, Adolphe Sax, dreamed up. The instruments are displayed behind glass: put on a headset, approach the cases, and music, often played on the actual instrument you're looking at, fills your ears.  There's a good gift shop here, and an excellent restaurant on the top floor with panoramic views over the city from the terrace.
