In 1859, on the occasion of his 100th birthday, the old Friedrichsplatz was renamed Schillerplatz. The important German poet was to be duly honored in the Nassau residence city. However, the city did not have an easy time with the classicist. The lime tree planted on Schillerplatz was soon moved to Warme Damm due to the traffic obstruction. In 1866, a monument to Schiller was erected in front of the old theater, today's Kaiser-Friedrich-Platz. In 1894, the lime tree on Warmer Damm was dug up again to make way for a monument to Kaiser Wilhelm, and Schiller himself had to be removed from his pedestal in 1897 for a monument to Kaiser Friedrich. It was not until 1905, the 100th anniversary of Schiller's death, that the monument on the park side of the theater put an end to the Schiller-less era in Wiesbaden.

Schillerplatz experienced its historic climax in 1866 when the takeover of Nassau by Prussia was announced by the reading of the proclamation of the Prussian King Wilhelm.
