The town of Taunusstein came into being on 1 October 1971 through the merger of the formerly self-governing communities of Bleidenstadt, Hahn, Neuhof, Seitzenhahn, Watzhahn and Wehen, whereupon Taunusstein was also given town rights.
In 1991, Dr.-Peter-Nikolaus-Platz, a square in the constituent community of Hahn, was dedicated and named after Taunusstein's longtime mayor.
