Brömserhof in Rüdesheim
Just a few steps from the Drosselgasse you'll find the Brömserhof. It hosts Germany's first Museum of Mechanical Music Instruments, also called "Siegfried's Mechanisches Musikkabinett". Parts of the building date back to 1310 which you will see when you take a tour through the museum.
Nowadays the museum holds a collection of 350 instruments from 3 centuries - from small music boxes from the 18th century up to large organs from funfairs (which I'm going to show you soon). In one of the windows you can see a glockenspiel with bells made out of ceramics.
