A room (room y) under the peristyle served as a cult room. It consisted of a room carved into the rock with masonry seats and a rectangular masonry altar inside. A terrcacotta altar, two clay lamps, and a marble sphere were found in the room. One of the lamps featured a relief depicting Jupiter with an eagle. The room had a mosaic floor. The room could be dated to the last phases of the house. It is not preserved today.
