Behind the entrance is a large nave with a Roman cross on the flat ceiling. A plain bench edges the side walls. Maltese crosses adorn the walls.
Straight ahead from the entrance is the sanctuary. It is large (nearly 4 meters by 2.5 meters). Seats in its sidea have angled armrests, they resemble throne chairs. The curved back wall has three tall arched recesses divided by pillars. A cross-shaped cutting appears at the base of each niched seat to hold sacred crosses. The base of the altar remains in the middle of the apse.
