Located on the south wall of the atrium was a rectangular niche shrine. Its interior was painted as imitation yellow marble, with a recessed area at the back wall for a statuette to be placed. It sat 1.6m from the ground. On the wall below the niche were two serpents meeting at an altar, which was constructed from stucco on a rectangular panel of red. Above and below the niche ran a stucco cornice. An associated painting of a genius with a cornucopia and patera was recorded nearby; however, it is uncertain exactly where this was as it had disappeared long before Boyce's time. The shrine was heavily damaged during WWII.
