It is the only such institution in Poland promoting knowledge about the Polish Underground State and its armed forces during World War II.
The idea behind the Home Army Museum is to provide a holistic picture of the Polish underground, its spiritual origins and the shape of patriotic heritage to the present day.
So far, the museum has collected more than 8,000 exhibits and more than 12,000 archives – mostly gifts of Army Soldiers and their families around the world – historical memorabilia, often with the tenor of relics.
One of the most precious exhibits is the diary of a famous major "Hubal" – Henryk Dobrzański, the first guerilla commander of the World War II in Europe.
The reconstruction of a detention cell in which after 1944 Polish Urząd Bezpieczeństwa (Department of Security) held members of the Home Army and postwar Freedom and Independence organisation gives the opportunity to experience the communist terror.
