Bad Cannstatt is not only the most populous, but also the oldest district of Stuttgart - here the settlement can be traced back to the Stone Age. The Bad Cannstatt City Museum shows important historical events and topics of local history in the medieval Klösterle-Scheuer.

Around 250,000 years ago people lived on the Neckar in Cannstatt - this is impressively illustrated by a travertine stone with the fossilized remains of a camp and slaughterhouse. The Romans secured the Limes against the Germans by building a cavalry fort "Auf der Steig" around 90 AD. A diorama shows various scenes of provincial Roman life in Cannstatt. The medieval townscape, which lasted well into the 19th century, is illustrated in a detailed town model.

On the upper floor, the Bad Cannstatt City Museum presents the permanent exhibition "Panorama Cannstatt", which reflects the different facets of Cannstatt as a Neckarstadt, royal city, literary city, hometown and much more. Other themes of the permanent exhibition include bathing life, the beginnings of industrialization and examples of prominent "Cannstatters". In regular special exhibitions, the city museum also deepens other exciting aspects of Cannstatt's history.
