In 1256, the area that became Bärenplatz was a ditch that was part of the second city wall. In 1513 the northern section was walled off to become the Bärengraben (Bear Pits). Then, in 1578 the bridge into the Käfigturm was demolished and in the next year, the southern section was filled in. The southern part of the plaza was used from the hay and wood market. Then in 1668/69 it became home to the Rossmarkt or horse market. When the Bärengraben were moved, the northern section was filled in and came to be known as Holzmarkt (Wood Market). The middle section was then known as Viehmarkt (Cattle Market). The plaza is first mentioned as Bärenplatz in the mid-19th Century.
