The Polish Crown Jewels are a collection of royal regalia that symbolize the authority and heritage of the Polish monarchy. These treasures include crowns, scepters, and orbs, which were used during coronation ceremonies and other significant state events. The most famous piece is the Crown of Bolesław I, named after the first King of Poland. Historically, the Crown Jewels were kept in the Wawel Cathedral in Kraków, a site of great importance in Polish history. However, many of these items were lost or destroyed during wars and invasions, particularly during the Swedish Deluge in the 17th century. Today, replicas are displayed in museums, while the original pieces remain a symbol of Poland's royal past.
