In 535, Sigismund's remains were recovered from the well on which a chapel was built, around which the village and monastery of
Saint-Sigismond later developed, and it was transferred and buried in the monastery at
Agaunum. hence he has become a
patron saint of the
Kingdom of Bohemia, now
Czech Republic. Charles IV built an altar in honor of Sigismund and also commissioned a reliquary for his head, which contradicts the claim that the head had been transferred to Rouffach by Dagobert II. It is possible that only a part of it was brought there. The emperor gave the saint's name to one of his sons, the later King
Sigismund of Hungary (who also became decades later King of Bohemia and Holy Roman Emperor). In 1424, Sigismund of Hungary constructed a church in the honor of Saint Sigismund in the
City of Buda. The same year, King Sigismund took the relics of Saint Sigismund from Prague and sent them to the Hungarian city of Varad to protect them from the
Hussites. of Saint Sigismund in
Płock Cathedral (2011)The relics and cult of Saint Sigismund also appeared in the
cathedral church in
Płock before the 13th century. It is unclear how they came to be there. They may have been brought by Bishop
Werner, who in 1166, on the order of Duke
Bolesław IV the Curly, traveled to Emperor
Frederick Barbarossa in an attempt to persuade him and prevent a planned military campaign against Poland. The mission was successful, and the bishop received a gift of
Saint Henry’s relics. On his return, near the border of
Meissen and Poland, he built a church dedicated to Saint Henry, where he consecrated an altar to both Saint Henry and Saint Sigismund. So it is possible that he also carried relics of Sigismund with him. An exceptionally rich reliquary bust is associated with the cult of Sigismund in Płock. It was commissioned by the Polish king
Casimir the Great between 1350 and 1356 and created in a Kraków workshop. The facial features of the bust closely resemble those of Casimir the Great as depicted on his tomb in
Wawel Cathedral, thus representing the founder himself. In 1370, after falling from his horse during a hunt, the king vowed to God and Saint Sigismund to rebuild the ruined cathedral in Płock. Although the king died shortly thereafter, his will was fulfilled by his chaplain, Jan of Skrzynno, who donated the royal reliquary bust to the cathedral. It was adorned with a 13th-century Piast crown and served as a reliquary of the saint. Looted by the Germans during World War II, it was returned to the Płock Cathedral in 1980. A Catalan legend, dating at least to the XVI century, has it that as a young man Sigismund travelled to Hispania and once there he heard about the hermits of the
Montseny mountain and decided to join them. As soon as he arrived at the mountain he found a hermit who initially welcomed him in his cave, but Sigismund, looking for a more secluded and solitary place, settled in a cave and lived there for two years dedicated to prayer and the interior life, feeding on herbs and other wild products. A place where his father came to look for him to integrate him into the government of his kingdom. This cave later became a sanctuary where hermits lived and pilgrims gathered to venerate the king saint, a tradition that still continues to this day each 1st of May. == Family and issue ==
