The side altar of the Christ Crucified was funded by father Jan Skinderowicz in Spytkowice and made by Cracovian wood carver Michał Dobkowski in 1754. It was painted in 1766 by Cracovian painter Józef Kopaciński. A reredos is one of works typical of wood carvers operating in Cracow in the first half of the 18th century, who willingly reproduced the works of Antoni Frączkiewicz. Michał Dobkowski was his apprentice.
