Wall 1, which was curved, was identified on the surface prior to the excavation (length c. 17 m; Fig. 2). The wall was built of large (average size 0.5 × 0.6 × 1.1 m) and very large ashlars (0.9 × 1.7 m) that were meticulously arranged as stretchers. Only the eastern face was exposed, to a height of three courses (height 1.75 m), while the western face remained covered with alluvium. Remains of light gray plaster were apparent on some of the stones, as were projections and hollows that may have been hewn to aid in transportation or to secure the stones in place. Wall 3 was exposed in the south of Sq A2 (length 3.1 m, width 0.6 m) and formed an acute angle where it met with W1. Only two fieldstones and one ashlar, arranged in a row, were preserved of this wall. Wall 2 (length 4.2 m, width 1.1 m) was discovered at the northern edge of Sq A1, below an accumulation of loose soil (thickness 0.1 m). It may have joined W1. Wall 4 (Fig. 3) was discovered in the center of Sq A1, west of W1, within collapsed stones; it may have been parallel to W1. Several fragments of light brown plaster containing gravel and charcoal inclusions were discovered between the stones. Another wall was exposed on the eastern bank of the streambed, c. 10 m northeast of the northern end of W1; it was constructed parallel to the bank, and continued north for several dozen meters. A few non-diagnostic pottery sherds were discovered in the two squares.
The massive construction of W1 and W2 probably indicates that they were part of a public building. The location of the walls in the streambed and the plaster remains on W1 seem to suggest that this building was associated with water utilization, perhaps of groundwater. The many wells and water reservoir that were previously discovered in the area, show that the high groundwater was exploited in ancient times.
