Flanking the Old Palace is Schillerplatz, an old town square with a monument to Friedrich Schiller, poet, philosopher, historian, and dramatist — one of Germany's most famous cultural giants. 

The square is the site of a flower market on Tuesday, Thursday, and Saturday mornings, and in December joins the Schlossplatz and Marktplatz, on either side of Schillerplatz, as home to the Christmas Market.

 One side of the square is formed by the Alte Kanzlei (Old Chancellery), and on the southwest side is the old Fruchtkasten (Granary) dating from 1390, and adjoining it, the choir of the Stiftskirche.
