Side altar was probably build, similarly to the high altar, around 1865-1870. Originally, based on a photography made in 1974, there was a pair of angels in the altar final. The main area of the altar contains a painting of the Most Sacred Heart of Jesus while the altar final contains the Ecce Homo (painting).
