The Robbers (Original title: Die Räuber) is the first drama by German playwright Friedrich Schiller. The play was published in 1781 and premiered on 13 January 1782 in Mannheim, Germany, and was inspired by Leisewitz' earlier play Julius of Tarent. The plot revolves around the conflict between two aristocratic brothers, Karl and Franz Moor. The charismatic but rebellious student Karl is deeply loved by his father. The younger brother, Franz, who appears as a cold, calculating villain, plots to wrest away Karl's inheritance. As the play unfolds, both Franz's motives and Karl's innocence and heroism are revealed to be complex.

The metal wheel with a height of around four meters is intended to relate to a crook's tine and was set up on the occasion of the staging of Friedrich Schiller's Die Räuber on a green area in front of the theater.
