An excavation square was opened, revealing an east–west oriented wall (W510; length 3.4 m, width 0.3 m; Fig. 1) that was built of a single row of ashlar stones. The wall, preserved a single course high, was partly damaged as a result of modern infrastructure work. Jar fragments that dated to the Byzantine period (sixth–seventh centuries CE; Fig. 2) were recovered from the wall, between the stones and from either side of it. The function of the wall could not be determined because of the limited scope of the excavation and the modern disturbances.
