Located in Brežice Castle, this is one of the finest and best preserved Baroque halls in all of Slovenia. It was constructed at the end of the 17th century, after the castle had come into the possession of the Attems family. The large hall is most notable for the ornate frescoes and murals that cover the ceilings and walls, which depict various mythological, classical and religious subjects, and were commissioned by Ignac Marija Attems, the first in a long line of the family's owners. The hall recently underwent extension renovations, and is open to visitors as part of the Posavje Museum, as well as during concerts and other events.
