The exhibition "#heritage" at the National Museum in Krakow is a contribution to a discussion on the subject of Polish identity. The exhibition features objects exclusively from the collection of the Krakow Museum, as these holdings define Polish culture in a special way. The emphasis placed on cultural continuity and finding recurring elements of national identity in both well-known and little-known works from different eras, even during the periods of no political sovereignty, is the most important thesis of the exhibition. Its structure is based on four categories taken from anthropological and historical studies of national cultures. These are: "territory", "language", "citizens" and "custom", the first one concerning the areas associated with a given culture and regarded by it as its own, the second one stressing the role of language in defining the national identity, the third one describing people associating themselves with a given culture and the fourth one making one aware that from the historical perspective nations can be defined by referring to their cultural sources rather than ethnical categories.
