Located in the centre of the west wall of the service atrium was a cult space. This consisted of a cult painting situated within an elaborate aedicula façade. The façade consisted of a shallow rectangular niche flanked by two corinthian engaged columns which supported the highly decorated stucco architrave and pediment. The tympanum was blue, with a patera, culter (ritual knife), and bucranium in stucco relief in the centre. The tympanum was surrounded on all three sides by triple bands of elaborate stucco painted red, blue, and yellow. The aedicula sat on a yellow base, around which ran a polychrome stucco cornice. At the back of the shallow niche was a painted scene depicting the central Genius holding a patera and an acerra. On each side of him stood a Lar, with rhyta and situlae. The lower portion of the painting was filled with a brown and yellow serpent, moving towards a square altar. On the altar were offerings of an egg and fruits. Across the top of the scene stretched three garlands with pendent taeniae.
