The exhibition shows the oldest and most important Polish regalia, as well as objects of religious cult: handicraft, clothes, paintings and sculptures, being donations of kings, bishops and members of nobility and ranked among the nation’s most precious treasures. The Museum exhibition presents the most precious objects of various times, organised according to their historical and artistic value rather than chronological order. Until recently most of the exhibits were kept in the Cathedral Treasury, which is one of the richest in Poland, even though it is now only a fraction of what it used to be, as it had been looted many times by invaders during various wars involving Poland. Nevertheless, the Wawel Cathedral Museum hosts one of the most valuable art collections in Poland, both in artistic and historical terms.
