Built at the request of Kaiser Wilhelm II., the Kurhaus as it stands today was constructed by Friedrich von Thiersch between 1904 and 1907 for six million Goldmarks and replaced the society building that had been erected by Christian Zais on this spot in 1810.

It is in Neo-Classical style. The imposing Ionic portal bears the Wiesbaden coat of arms with its three lilies and the phras "Aquis Mattiacis"  i.e. the waters of the Mattiaci.

 
The Kurhaus was restored in 1987 true to its original style and is equipped with the latest in communications technology. National and international congresses, meetings, concerts and exhibitions are held here, as well as open-air concerts of classical music, the Jazz Band Ball and the Kurhaus New Year's Eve party.
