The new town hall was built during the reign of Lord Mayor Karl Bernhard von Ibell, under whose administration Wiesbaden experienced a great upswing, the population grew rapidly and administrative tasks increased. The old town hall had become too small, many municipal authorities had been outsourced and the spa services had been taken over by the city administration. In 1868, the town acquired the former Koppensteiner Hof from Chief Forester Carl-Reinhard Dern and used the manor house premises for the municipal authorities. authorities.

Plans for the construction of a new town hall had already existed since 1876. In 1881, further houses were purchased and demolished to create the building site for the new town hall. The Munich architect Georg von Hauberrisser, a specialist in town hall buildings, won a competition held in 1882. The main façade is aligned parallel to the Marktkirche, exactly opposite the city palace, and thus points to the claim to representation of local self-government. The foundation stone for the new building was laid in 1884.

The building was erected on a pentagonal ground plan in the neo-Renaissance style with a variety of architectural motifs and rich sculptural decoration. The Palatinate sandstone façades were richly structured and vividly designed with bay windows and gables. The new building was occupied in October 1887. A wide open staircase led to the higher first floor. The interior of the building was dominated by the vaulted entrance hall and the ballroom on the second floor, in front of which the balcony resting on four pillars was decorated with four allegorical figures by the Wiesbaden sculptor Hermann Schies. They represent the virtues of strength, justice, diligence and charity. It was not until 1898 that the banqueting hall was decorated with paintings by Wiesbaden painters Kaspar Kögler and Adalbert von Rößler. On the night of the bombing from February 2 to 3, 1945, around two thirds of the new town hall was destroyed. In 1951, the reconstruction was completed in a simplified style. The modernization of the interior was carried out with respect for the historical structures. Many details of the original furnishings have been preserved.

The new town hall, the seat of the Lord Mayor and the main administration of the municipal authorities, has a representative, spacious double staircase, a ceremonial hall with a simple elegance and a modern, functional meeting room for the city councillors. The lower "Ratskeller" is a popular restaurant for the citizens of Wiesbaden.
