The sculpture of St. Adalbert, along with the whole high altar, was created in the Cracovian sculpture workshop of Władysław Druciak in 1914. His works are described as an example of historicism in sacred sculpture of the early 20th century. Saint Adalbert lived in 956-997. In 997, he set off to Poland and then to Prussia in order to convert pagans. He suffered a martyr's death, probably pierced with spears. In iconography, Saint Adalbers is often presented with an oar in his hand, a reference to a history, by which the bishop set off to convert pagans in Prussia on a boat, crossing the Vistula.
