In the heart of town, named after the pronounced colour of its façade, this is one of the most noticeable buildings. This 1756 mansion was owned by Johan Heinrich Scheibler, one of the most prominent cloth producers and traders in town. His famous 18th century fabrics found their way to the courts of the French king and the Turkish sultan. The mansion is now a museum, boasting a full historic interior with all the grand features of the Rococo / Louis XV style that marked the wealth of its former proprietor. Of particular interest is the three story open-newel spiral staircase, decorated with wood carvings depicting all the main steps in the cloth production. Two surviving original cloth sample books showcase the huge collection of cloths designed and produced here. Guided tours start every hour.
