The Main Altarpiece
Probably earlier than the main altarpiece, this side retablo represents Souls in Purgatory. The principal painting is dated 1733 and is divided into three levels; Heaven above, with the Holy Trinity; Earth in the center, and Purgatory below.
Nicholas gestures to a soul with his robe cord, saving him from Purgatory. More souls, several in chains are shown in the smaller panels along the predella below.
