The Sorbisches Museum, in the salt-house wing of the Ortenburg, is the world's principal museum of Sorbian culture, language, and history. The exhibits cover the arrival of the Slavic Milceni in the region around the 6th century, the survival of the language under Saxon, Prussian, and Nazi rule, and the contemporary Sorbian-speaking villages scattered through Lusatia.
The strongest sections are the textile and folk-art galleries — the elaborate embroidered Easter eggs (kraslicy), the headdresses and bridal costumes, the carved wooden interiors of village houses. Captions are in German, Upper Sorbian, and English. Closed Mondays.
