The "House of Dionysos", thus named after the famous mosaic floor depicting Dionysos riding a panther, is a good example of a private residence, dating from the last quarter of the 2nd century B.C. A covered passage leads from the entrance to a peristyle court, on which open the rooms of the ground floor. At the centre of the court there is a cistern for the collection of water, covered with a splendid mosaic floor. A stone stairway leads to the elegant private rooms of the upper storey.

The House of Dionysus was large enough to have mutiple stories although the upper floor has since collapsed. Along with the central mosaic, the decorative plastering on the walls in some rooms is still visible. Viewed from higher up the hill, the elaborate floor is surrounded by eight Doric columns. Private rooms upstairs would have had a view down into this central court. This home dates from around 125 BC and several artifacts from it can be seen in the museum including dice and utensils.
