This is the main room in this palace. Here the gentlemen received their guests, here we see all the most important surviving elements of the manor's decoration. The room is large, with only two windows, and they are small, so there is little light. That is why it was called the "Pustamsė hall". Polychrome research has been carried out and the entire decor of the manor's palace has been clarified. As you can see, the ceiling is ornate, although only half of the room is revealed in all its beauty. The other half was already in a state of emergency during the restoration, the plaster had already crumbled, so only the central part has been preserved. The wall frieze, the geometric decoration of the ceiling, the floral ornaments, rosettes, acanthus, which no one saw, but when drawing, they imagined the extraordinary beauty of distant lands, the leaf create a mysterious, moody image for the room. These are features of romantic classicism, reflecting the fashion for decorating buildings in Lithuania at that time. In the corner is a large white brick stove that heated not only this room. And underfoot, there is geometric-patterned oak and ash parquet: restorers replaced only small worn fragments, and the entire floor has survived.
Now this hall is a venue for concerts, meetings, conferences. Exhibitions are held here, and educational and tasting programs are held.
The wall paintings of the small rooms adjacent to this hall may depict giants who, while smoking their pipes, demolished the Kupiškis Mound. Apparently, this room between the large halls was once a smoking room, because in the compositions above the doors, called supraportas, we see pipers and their two pipes.
