The brothers Florian and Nikolaus Kolhammer offer primarily high-quality art objects of Viennese Art Nouveau in the middle of the art district and in the immediate vicinity of St. Stephen’s Cathedral. The assortment includes products of the Wiener Werkstätte, art nouveau glass – especially the glass manufactory Johann Loetz-Witwe – as well as paintings. Another specialty are the timelessly modern art objects of the Hagenauer workshop.
