It exhibits unique and valuable archaeological finds that tell of the history, archaeology, ethnic culture and folk art heritage of the Semigallia region. The museum houses relics of the old Semigallian way of life and warfare, reconstructions of Semigallian clothing (archaeological costumes from the 9th and 12th centuries by the author D. Steponavičienė), and teach interesting historical facts from the earliest times to the present day. This is the only museum to show the exceptional finds of an 11th century tomb from the rich Semigallian burial site of Kurmaičiai-Linksmėnai, where the deceased were buried with a large number of grave goods, including five collars, wrap-around bracelets, and cross-studs covered with silver plaques. Next to the exhibition are the tombs of 11th century male soldiers, with the characteristic broad-bladed fighting knives, swords and thrusting spears, a single-bladed sword and knife, a bowshaped poppy pin and a silver collar.
