This is probably a viridarium (Roman garden) with porticoes, a terrace with a garden for pleasure and relaxation that is adorned with rare plants and decorative elements. In the axis of the garden stands the well whose  coping is cut out of a single block of stone.  Overview The garden measures 14 by 9 meters. The well Two juxtaposed ponds, one circular with a diameter of 3 m and a depth of 0.70 m, the other rectangular (3.10 m by 2.30 m), decorated this garden. Their bottoms consist of an assembly of briquettes in the "opus spicatum" (herringbone pattern) style. The circular basin and the well The rectangular basin The floor of the circular basin in opus spicatum In its current state, the garden is crossed in the north - south direction by the foundations of the west wall of the paleochristian basilica which breaks the perspective. Remnants of the stylobate and the gutter It was surrounded on its four sides by porticoes of unequal widths. The stylobate (foundation of a colonnade), of which only a part of the south side remains, supported sixteen columns providing three inter-column spaces on the short sides and five on the large ones. A gutter for the collection of rainwater ran down a pipe connected to the large drain of street C. Four sections of sandstone columns, from a Gallo-Roman house on Rue Calixte Camelle in NARBONNE, which has now disappeared, have been erected and represent the porticoes. Evocation of the peristyle In the background, foundations of the basilica wall This rectangular peristyle with a total area of 180 m² (about 1950 sqft) measures 22.5 m (about 75 ft) in the north-west to south-east direction and 13.6 m (about 45 ft) in the north-east to south-west direction.  The south-facing walkway is the most spacious. The floor of the peristyle was covered with a black  mosaic and white stripes.
