The fact that Wangen has an Eichendorff Museum is related to Germany's post-war history. After the Second World War, many refugees from the former German eastern territories flocked to the town, which had been almost completely spared from the events of the war. A Silesian artists' colony was founded. Showrooms were set up in the houses of the settlement on the Atzenberg, which were to be successor institutions to predecessor museums in Upper Silesia destroyed by the war. The writer Willibald Köhler, who had looked after the Eichendorff memorial in the house in Neisse where the poet had died, set up a German Eichendorff Museum in Wangen in 1954 with memorabilia and objects collected by him and took over its management. After his death, Köhler's collection, which also houses a small archive, became the property of the town. Since 1986 it has been on display in the former dyer's house near the powder tower, and two years later it was integrated into the ensemble of the municipal museums.
