Part of an underground industrial installation (min. width 3.65 m; preserved height 3.65 m; Fig. 1), which was hewn in kurkar bedrock and used for storing liquid, was excavated. The walls, cast of coarse material and small stones, were coated with several layers of hydraulic plaster. The floor was a white industrial mosaic composed of medium-sized tesserae. The complete plan of the installation was not ascertained due to the vast damage caused to it.
The installation was filled with black soil that contained potsherds from the Byzantine period (fifth–seventh centuries CE) together with modern debris (glass and ceramic tiles) and animal bones. The installation should be dated to the Byzantine period based on the manner of its construction, the plaster, the mosaic and the potsherds in the fill.
