A dedicated museum to Johann Sebastian Bach, born in Eisenach in 1685. The permanent exhibition occupies rooms arranged as a 17th-century Thuringian household, with original instruments from Bach's period — including a clavichord, a lute-harpsichord, and various period keyboards — that are played live at regular demonstrations throughout the day.
The exhibits trace Bach's life from Eisenach through his posts at Arnstadt, Mühlhausen, Weimar, and Leipzig, with sheet music, portraits, and contextual material about Baroque musical culture. There is also a "walk-in music piece" installation using bars from the Christmas Oratorio. The museum is on the Frauenplan, a five-minute walk from the Marktplatz.
