This museum has clearly, uh, struck a chord: there are now five of them in town, with over 25,000 music boxes on display. Actually everything is for sale. While it's mostly new stuff for the tourist market, on the 2nd floor of this main museum (a charming red-brick structure from 1912) there are some truly impressive antiques.
There's even music box sushi. As if you hadn't seen it all.
