Though she was venerated soon after her death, it wasn’t until the papacy of Pope John Paul II that the idea to canonise the “most Christian queen” (as proclaimed in a homily given at her funeral) emerged. Her claims to sainthood were largely based on legend and impossible to verify 600 years down the line, but the appeal of having a saint among the Polish rulers was large. The proof included a single instance of hearing Christ speak while praying in front of a large crucifix, bringing a drowned boy back to life by covering him with a mantle, and a curious case of leaving a footprint in already-set plaster while giving a poor stonemason a golden buckle from her shoe (no, the Queen did not weigh 300 pounds, good guess though). The “100% authentic” footprint in question is still visible and lovingly preserved on the facade of the Church of the Visitation of the Blessed Virgin Mary at ul. Karmelicka 19 - find it on the corner of the building to the right of the entrance, just above ground-level. The Church decided on the sufficiency of these claims and Queen Jadwiga added another title to her name in 1997.
