This museum contains fascinating artefacts, including the founding documents of Jasna Góra from 1382 and a cross made from the steel of the World Trade Center, destroyed in New York on 11 September 2001. Particularly moving are rosaries made from breadcrumbs by concentration camp prisoners. Lech Wałęsa’s 1983 Nobel Peace Prize, donated by its recipient, can be found beyond the Father Kordecki Conference Room.
