In the composition of the architectural arcade, Christ on the cross in the center, to the right is the standing figure of St. John the Evangelist, while to the left are the figures of the Virgin Mary and Mary Magdalene. In the background is a vast mountainous landscape. At the bottom the inscription reads: “Der für uns geKreuzigt worden” (He who was crucified for us).
In the five windows of the south aisle are stained glass windows, whose author was Joseph M. Machhausen of Koblenz. The theme of these masterpieces with strong, saturated colors is the Sorrowful Mysteries. Originally, the arrangement of scenes began with the “Prayer in the Garden” in the south chapel window and ended with the “Crucifixion” in the fourth window of the south aisle. However, as a result of extensive restoration of the glazing, the former order was reversed.
The stained glass windows, modeled on Gothic glass, were made thanks to the patronage of Warmian Bishop Philip Kremenz, who came from Koblenz. He contributed to the creation of high-quality stained-glass windows in the Diocese of Warmia in Frombork and Proskinia, among others, and presumably, based on the characteristics typical of the same artist, in Bartag, Bartoszyce, Eldyty Wielkie and Radostow.
The stained glass windows in the church in Święta Lipka are works in an eclectic style adapted to the church’s Baroque interior. The works of Joseph M. Machhausen are distinguished by the precise drawing of the faces and bodies of the figures depicted. In addition, the stained glass windows in Święta Lipka, bear inscriptions and the signature of the workshop. It is possible that the stained glass windows also adorned the windows of the northern nave, but it is not known when and under what circumstances they were dismantled.
