The main hall is adorned by two larger than life statues of female allegorical figures representing Industry and Agriculture. They are the work of Otto Geyer.[4] Geyer also sculpted the figured reliefs adorning the historical façade, both of which bear his signature.

The main hall also used to display two frescos by Hermann Knackfuss, painted in 1885, one depicting William I's visit of the fortress Fort Kronprinz in Hausbergen (now Fort Foch, Niederhausbergen), belonging to the fortified belt around Strasbourg, on 3 May 1877 and the other one, as a historical parallel, depicting in Frederick I's arrival in Haguenau in 1164. The two works of art, called Im alten Reich and Im neuen Reich ("In the old Empire" and "In the new Empire") were removed at some point in the 20th century and are lost.
