An area (L400; 6.0×7.5 m; Figs. 2, 3) was excavated and its surface that served as the ceiling of the cistern was exposed, as well as an opening for drawing water and a cupmark. The northwestern side of the cistern, which was damaged by mechanical equipment when the water pipe was being installed, was also excavated. The cistern itself was not excavated due to the possible collapse of its ceiling.
 
The opening through which water was drawn was rock-hewn and circular (diam. 0.9 m, depth 0.22 m) and sealed with a large irregular-shaped fieldstone (0.5×0.7 m, height 0.31; Fig. 4). A cupmark hewn in the bedrock (L401; diam. 0.2 m, depth 0.18 m; Fig. 5) was discovered c. 2.5 m east of the opening. The elliptical cistern (9×12 m, depth 3.5 m) was hewn in limestone bedrock and was coated with white gravelly plaster from its bottom to midway up its side (Fig. 6). Alluvium penetrated into the opening after the cistern was no longer in use (Fig. 7). Two layers were exposed in the excavation on the northwestern side (L402; 1×2 m; Fig. 8); an upper layer (thickness 0.5 m) that was an accumulation of brown alluvium with medium and large stones and potsherds from the Iron Age and Byzantine period, and a lower layer that consisted of light colored soil, reaching the bottom of the cistern (max. thickness 0.4 m; Fig. 9) and several non-diagnostic potsherds.
 
Since only a small portion of the cistern was excavated and the ceramic finds were eroded, it is impossible to date the time of its construction or use. Archaeological evidence in the region points to the existence of a Byzantine–Early Islamic monastery and a Jewish settlement from the Early Roman period at nearby Khirbat Umm Leisun (Seligman and Abu Raya 2002). It seems that a settlement hiatus transpired in the region from the Islamic period until the early twentieth century CE and the construction of the village. Therefore, it can be cautiously suggested that the cistern was installed in one of these periods.
