Memorial Museum Siberia tells the story of Polish citizens deported east under Russian and Soviet rule, with particular attention to Bialystok and the surrounding region. It is a serious, modern museum built around exile, forced journeys, family memory, and the long shadow of Siberia in Polish history.
This is not a light stop, but it gives Bialystok a sharper historical frame. Visit when you have time to slow down: the subject is heavy, and the museum is strongest when read as personal testimony rather than a simple chronology.
