The Dzieduszycki Museum rooms are on the first floor and their design faithfully reflects decor from the first quarter of the 19th century. It also reflects the heritage of the Dzieduszycki family, paying special attention to the activities of the first heir Włodzimierz Dzieduszycki. Original palace furnishings (stored after the War in the Museum in Jarosław) help recreate the character of the times, and are displayed in the rotunda on the first floor. Portraits (colour photo reproductions) of members and relatives of the Dzieduszycki family – bequeathed by the Association of the Dzieduszycki Family of the Sas Coat of Arms – can be seen in the rooms on the ground floor and in the hall on the first floor.
