In the cross of the cathedral there is an altar dedicated to Saint Stanislaw. The altar was found by Marcin Szyszkowski and made by John Trevano. The altar is decorated with 8 figures of saints related with Poland: Stanislaw, Adalbert, Wenceslaus I duke of Bohemia, Casimir Jagiellon, Hyacinth Odrowąż, Florian, Sigismund, Ignatius of Loyola.
  The coffin hold by four angels contains the relic of Saint Stanislaw. Saint Stanislaw was the bishop of Krakow keeping this position in the mid 11th century. In 1079 he was killed by the king Boleslaw the Cruel (see the legend). Saint Stanislaw was canonized in Assisi, Italy in 1253 and his relics placed in the cross of the church. The coffin is decorated with following scenes: 'Buying a village by bishop Stanislaw', 'Raising of Peter by bishop Stanisław', 'Killing bishop Stanisław', 'Eagels flying over the body of bishop Stanisław', Bishop Stanisław in the coffin', 'Moving from Skałka to the Wawel Cathedral', 'Raising of three death people', 'Canonisation of the bishop Stanisław in Asisi', 'Saint Hyacinth', 'Battle of Grunwald'.
  Next to the coffin there is a silver book containing blood of the pope John Paul II. In 2011 the pope was beatified, in 2014 canonised. Soon after some drops of his blood were transfered to different sanctuaries as relics. In 1979 John Paul II for the first time as the pope visited the cathedral. In that time left special candle, staying until today on the right side of the altar.

  Below, on the floor there is a conmemorative plaque and grave of the cardinal Adam Stefan Sapieha. The cardinal performed his function during World War II, later 1 of November gave priesthood to Karol Wojtyla future pope John Paul II.
