After the removal of a modern fill layer from the excavation area (5 × 10 m; thickness 0.8 m), the general outline of a bedrock-hewn rectangular structure that was filled with stone collapse (0.9–1.2 × 1.6–2.8 m; depth 0.9–1.2 m; Fig. 2), was noted. The collapse (Loci 100–102) in the structure turned out to be intentional. The tamped fill served as a blockage, composed of dressed limestone, small and medium-sized pieces of flint, large quantities of potsherds and fragments of stone vessels. A wall (W2000), built of medium-sized roughly hewn fieldstones, extended across the structure and apparently served as a low partition (Figs. 3, 4). The floor of the structure was the soft limestone bedrock and no walls or remains of plaster were discerned on it. A hewn opening (0.8 m wide; L105) in the structure’s western wall led to a rock-cut cell (1.2 × 1.2 m; L106). To the west of the opening was the beginning of another unit that had been destroyed during earlier development work and remained beyond the limits of the excavation. The remains indicate that the structure was partly rock-cut and partly built. Among the stones in the collapse were dressed cornerstones, probably used for the joint between the wall and the ceiling. No occupation layer was discerned on the floor and the blockage attests to the intentional cessation of activities in the building. The ceramic assemblage included bowls (Fig. 5:1, 2), cooking pots (Fig. 5:3–6), jars (Fig. 5:7–14), jugs (Fig. 5:15–18), juglets (Fig. 5:19–26), flasks (Fig. 5:27–29) and a lamp (Fig. 5:30). The stone vessels included bowls (Fig. 6:1, 2) and cups (Fig. 6:3–6). The assemblage is dated to the Early Roman period (first century BCE–second century CE). A prefect coin from the time of Augustus (6–12 CE; IAA 99433) was found. The dating of the finds is identical to that of the previous excavations at the site (Permit No. A-4325), which documented burial caves from the Early Roman period and cave dwellings of the Hellenistic period. It seems that the structure was part of Horbat Zawaha, located at the end of the spur, above and adjacent to the aqueduct, where building remains, burial caves and numerous potsherds of the Early Roman period were documented.
