Stone Clearance Heaps.Two stone-clearance heaps were examined (L100, L300). A trial square was opened around Stone Heap 100 (Fig. 2) in order to determine whether it was a burial mound; No diagnostic items were discovered in the heap. Stone Heap 300 was retained by a low wall (W301; Fig. 3); only one of its sides was exposed. No diagnostic finds were discovered in this heap as well.
Field Towers. Two field towers of different plans were uncovered: A rectangular tower (L200) and a round one (L500), both built of ashlars and fieldstones. Tower 200 (2.8 × 3.7 m; Figs. 4, 5) was built on a leveled surface that served as a floor. Its walls were preserved to a height of 0.8 m, and its opening was set in its northern wall (width 0.5 m). Tower 500 (preserved height 1.6 m, inner diam. 3 m; Figs. 6, 7) had a floor of tamped earth with several irregularly shaped floor tiles. The tower’s opening (width 0.8 m) faced south. Jars (Fig. 8:1, 2), a cooking pot (Fig. 8:3) and a glass bottle (Fig. 8:4) dating from the Late Roman and Byzantine periods (late fourth–sixth centuries CE) were found in Towers. The field towers seem to have served for storage, guarding and temporary dwelling.
Building (L400;6.0 × 6.4 m). The building was constructed of large, roughly hewn stones (Figs. 9–11) and was found covered with an impressive collapse. A probe excavated in the building’s southeastern corner revealed that it was built of stones arranged as headers and stretchers; a course of stones that was laid widthwise was also exposed. Remains of fieldstone walls that delineated a courtyard (9 × 15 m) were discerned south of the building. The courtyard was apparently bisected by a low wall. Two probes excavated in the courtyard yielded no diagnostic finds.
Although Building 400 stands out prominently in the area, it was not documented in previous surveys. The structure differed from the Field Towers 200 and 500, in both size and quality of its construction. The heavy collapse attests to walls that rose to a great height and probably to partition walls as well. In the absence of a comprehensive excavation it is difficult to know whether this is a particularly large field tower of the type known in western Samaria (Dar 1986:93), or if it served a different function. It is possible that the structure was erected as a stronghold related to the network of Roman roads between Nahal ʽIron and Nahal Shekhem. Sections of one of the roads that were found in the Menashe Hill Country Survey (Route C16) ran from Ya‘bed by way of Tura el-Gharbiyya, Nazlet Zeid, near Building 400 and to Kh. Umm er-Rihan (Zertal and Mirkam 2000:30). There was an intersection at or near Kh. Umm Richan, whence the roads led north toward Wadi ʽAra (Dar, Tepper and Safrai 1986:21–22), northeast via ʽEinan to Taʽanakh and southeast to Jenin, which is Roman Ginae—Route C17 in the Menashe Hill Country Survey (Zertal and Mirkam 2000:30).
It seems that most of the remains belong to the agricultural hinterland of the settlement at Kh. Umm er-Rihan, and add to the long list of other remains of agricultural activity in the northwestern region of Samaria (Maharian 2001a, 2001b; Aizik and Peleg 2009a; 2009b).
