The painting "Saint Joseph" from the end of the 18th century, inserted into the side altar from the foundation of father Walenty Bańkowski. Saint Joseph is depicted in a traditional iconographic convention, i.e. with Infant Jesus in his arms (to show him as the guardian and protector of the Son of God) and with a white lily in his hand – a symbol of chastity.
