The statues of Peter and Paul apostles were created together with the high altar in 1712. They were most probably created by the workshop of Anthony Frączkiewicz. Peter was the brother of St. Andrew, a fisherman, who joined Christ and became his apostle. In iconography, one of his attributes are keys.
