From the 34 guard and gate towers of the medieval city walls, there are only three remaining, namely Alexanderturm, Holzturm, and Eisenturm. Built around 1240. The Eisenturm is a six-storey solid stone tower near the site of the former iron market on the banks of the Rhine. Hence its name, which translates to "iron tower".
The Eisenturm served as a watchtower and a military prison. Today, it is a venue for art exhibitions.
Located between the modern City Hall, the thoroughfare of Rheinstrasse, and the "Am Brand" shopping centre, the tower has not lost any of its medieval charm. The Kunstverein Eisenturm Mainz e. V., established in 1975, refurbished the building which now houses an impressive collection of contemporary art.
