„Or, a deer sable passant; in the chief, ahead a bendy wheat ear vert and rear an oak leave vert sinister.“ The arms are derived from the Counts of Stolberg, the powerful family in the area and followers of the extincted Lords of Westheim, who showed a deer on their arms. The wheat ear symbolises the aggriculture and the oak leave the better wooded area.
