A small-town arcade house from Alwernia dates back to 1825 and is a characteristic example of the market square development. It has two rooms in the front, an alcove and a pantry in the back. One of the rooms contains the exhibition titled '1930s Mixed-Goods Shop' with equipment from shops in Trzebinia and Jaworzno on display. It is also possible to buy souvenirs and contemporary handicraft there. Other rooms house the Poviat Tourist Information Centre, offices and storage.
