The wall (W103; width 0.55 m) was built of three rows of small, undressed kurkar stones and survived three courses high, including a single foundation course below the floor level. A very thick floor (L104; thickness 0.1 m), which abutted the northern side of the wall and sloped slightly northward, was composed of four layers: An upper layer of white hydraulic plaster (1.5 cm), a layer of gray mortar (3 cm), another layer of smooth white plaster (0.5 cm) and a bottom layer of gray mortar that contained numerous carbon inclusions (4–5 cm); both plaster and mortar layers were mixed with crushed shells (Fig. 2). The bedding below the floor consisted of two courses of fieldstones with hamra soil. The stones in the lower course were slightly larger than those in the upper course, which had a fill of dark soil between them (L106). The thickness of the floor and the quality of its bedding foundations probably stemmed from the necessity to overcome the instability of the alluvial soil in the region.
The pottery finds included a few fragments of cooking pots from the Byzantine period found above and below the floor (L104). A handle fragment of a Middle Bronze Age juglet (Yannai, pers. comm.) was recovered from the alluvium above the installation. It is thought to have originated from one of the tombs from the period that are located in the second kurkar ridge, west of the site (Map of Herzliyya [69], Sites 20, 74).
