The collection boasts approximately 4,000 inventory items. These are exhibits which mostly originate from the area of the former Bielsko voivodeship. The largest number, dating from the end of the 19th century to modern times, constitute elements of folk costume from the Cieszyn, Pszczyna and Wilamowice areas, those worn by the highlanders of the Silesian Beskids, and by the Lach people, predominantly in the area around Biała.  

Of particular interest is the collection of silver jewellery usually worn by women from the Cieszyn area. The jewellery includes bands, breastplates (orpanty), brooches and breastpins (hoczki) for bodices (żywotki). The latter collection amounts to almost 1,500 pieces. These were made at the end of the 19th century and in the first half of the 20th century, using moulding and casting methods as well as filigree techniques.  

Some of the more interesting examples of the cast breastpins are those with figurative motifs – lions, two-headed eagles, winged dragons, mermaids, angels, cupids, stags, peacocks and doves. There are also floral motifs. The filigree breastpins are most often in the shape of stylised leaves and flowers with s-shaped, spiral and circular patterns. There are also numerous bodices (żywotki) and traditional caps (czepki) with lacy decorations made using bobbin, crocheted or needle lace techniques.

The collection also includes decorative fabrics, a wide range of embroidered items - in single or many colours, cross-stitch, flat embroidery, broderie anglaise, cutwork - and crocheted lace from Koniaków.

The folk-art embraces paintings, sculptures and chromolithographs from an earlier age as well as modern art: sculptures, reliefs, paintings and images on glass. Carved wooden toys and birds also form part of the collection.

Traditional and ritual art is characterised by nativity scenes, masks and the traditional stars carried by carol singers. The nativity scenes form a collection comprising a variety of styles, ranging from paper-covered boxes containing a handful of plywood or cardboard figures, through thatched buildings reminiscent of peasant cottages containing wooden figures, to church architecture typically found in puppet show nativity scenes. Two of them resemble the architectural style of Bielsko and Biala. The oldest nativity scene, created by an unknown artist at the turn of the 20th century, hails from Godziszka.  The masks are usually made of wood. The most popular of these depict the Jew, the Devil, Death, as well as Goats, which traditionally accompany carol singers in Poland. The collection also includes costumes of Gypsy folk, Dziechciarz (the ‘Tar man’), as well as Horses from the troupe called Dziady (Forefathers) who continue to go carol-singing  to this day on New Year’s Eve and New Year’s Day in certain villages in the Żywiec Beskid Mountains.

The department also houses household equipment and objects, items relating to folk industry crafts, mainly weaving and wood processing, as well as farming and animal husbandry tools.
