Lateral towers and a Baroque entrance have been added in 1864.
The Museum is characterized by rather small thematic units exhibited in separate rooms, providing it with a special kind of charm and liveliness.
A selection from the Ethnographic Collection - which is the richest one at the Museum - shows the interior of a typical three-room rural house from the beginning of the century, as well as the region's traditional way of living. On display are also items associated with popular handicraft - especially textile, timber products, and traditional folk musical instruments.
The pottery products from Fericanci constitute a unit apart. This, once highly renowned Slavonia's pottery centre, has been presented in the form of a potter's workshop with all the necessary tools and equipment, as well as a rich selection of products.
The Nasice region's historical review has been presented using archeological finds, as well as historical, and cultural-historical materials collected in the area.
Distinguished persons born in Nasice or their surroundings: Izidor Krsnjavi, Dora Pejacevic, Hinko Juhn, and Mate Benkovic, have their own separate memorial rooms. The "Izidor Krsnjavi" Gallery is also a part of the Museum's holdings. Its exhibition on permanent display consists of a selection of works by artists associated with Nasice region through origin, birth, or residence. There is also a separate collection consisting of the works by ceramists participating in the "Hinko Juhn" art colony. Temporary exhibitions take place at the mansion's Grand Salon. Hunting and mineralogical collections are currently under establishment (the holdings are already there, soon about to be put on display), along with the Pejacevic Family Collection.
Since the Museum's very establishment, considerable efforts have been invested into the expansion of its holdings, particularly those ethnographic, by Prof. Ivana Jurkovic, former Museum's Director, now retired.
