Two excavation squares were opened around the pit excavated by the electric company (L101; Fig. 2). The remains of a massive foundation (L104; length 8.5 m, width 1.8 m, height 0.9–1.1 m; Figs. 3, 4), built of fieldstones and river pebbles (max. length 0.2 m) bonded with gray-white mortar, were discovered below a layer of brown alluvium (L100–L103, L105, L106; depth 0.6 m). Fragments of a bowl (Fig. 5:1) and jars (Fig. 5:2–4) from the first–third centuries CE were found in the alluvium that covered the foundation. Several glass vessels dated to the fourth and early fifth centuries CE were also discovered. The foundation evidently carried a previously unknown Roman-period aqueduct.
