Against the south wall of the garden stood a nymphaeum. This took the form of an aedicula, smaller than typical, with two plain columns flanking a vaulted niche with a simple pediment on top with a single gabled roof. This central niche contained four steps. A statue of Silenus was found in the centre from whose wineskin fell water into the pool below which was divided into three compartments. The façade of the structure was decorated with mosaic. At the base was a mosaic of a Nilotic scene, showing pygmies in a boat amongst reeds with a hippopotamus between them and a reed structure. Palm leaves can be seen behind them. The scene was outlined in shells and would have been under the flow of the water from the fountain above. The rest of the façade was just as highly decorated, with blue, green, red, and cream mosaic details with shells used to outline different sections. The interior of the niche was decorated to match the façade. The interior walls featured large trees in the centre on both sides. The arch of the ceiling featured panels depicting birds with unrecognisable objects and plants in between panels of geometric and floral designs. The back of the niche was decorated with three panels, the two outer panels featuring garlands in the shape of crosses, with the central panel left almost undecorated (presumably as it would have been blocked by the statue of Silenus). The nymphaeum dates to the early first century A.D. prior to the earthquake.
