In the triclinium on the lower level of the house was a nymphaeum shrine. This was buit to represent a grotto-like space. The nymphaeum had the form of a large curved niche. Water entered the space through a staircase in the centre of the niche which was set into a sloped structure. It would then fall into a masonry basin that extended across the width of the room. This basin had three niches on its front, two rectangular ones flanking the structure, and a larger curved one in the centre. The nymphaeum was decorated with paintings, shells, mosaics, and marble veneering. However, of this decoration, only patches of mosaic were visible on the sides of the niche opening showing a blue background with floral motifs. Small windows were present on either side allowing light into the room. Opposite the nymphaeum was a large window that would have provided a view of the coast. The room has been dated to the last phases of Pompeii, added following the earthquake in 62 A.D.
