The museum consists of 11 spaces that guide visitors through the history of the Lubomirski family against the background of the history of Poland and Europe.

Each room presents a different fragment of this story, showing how the family’s fate intertwined with important historical events. The objects presented in the museum come from the Lubomirski Princes Collection, gathered by successive generations.

Among the exhibits are both works of art, historical objects, and memorabilia related to the family heritage. A special place is occupied by the permanent exhibition, which includes objects dating from ancient Rome up to modern and contemporary times. The collected holdings present an enormous variety — they include paintings, documents, sculptures, militaria, and everyday objects that allow for a better understanding of the realities of life over the centuries. They create a multidimensional image of the past, combining artistic, representative, and utility objects, which allows one to trace both great history and the everyday life of past epochs.

The collection also includes works by outstanding artists such as Rembrandt, Albrecht Dürer, Jacopo Tintoretto, Jan de Herdt, Giovanni Battista Lampi, Per Krafft the Elder, Marcello Bacciarelli, Élisabeth Vigée Le Brun, Julian Fałat, Jacek Malczewski, Teodor Axentowicz, and Leon Wyczółkowski, which additionally emphasizes the rank and diversity of the collection.
