The former Saalhof Chapel dating back to the Hohenstaufen era (around 1120) is the oldest building in Frankfurt's old quarter and now forms part of the Historical Museum. Since 1878 the Historical Museum on Römerberg square has documented the history of Frankfurt with a collection of approximately 600,000 exhibits and works of art. The museum consists of various sections: an art collection - primarily paintings and drawings, a textiles collection, a coin cabinet, craft objects and a collection of old toys. Closed on Mondays. Guided tours on request.
