The First Phase. A large building was constructed; it consisted of a wall on its southern side (W4; Fig. 3) and four walls perpendicular to it (W6, W18, W20 and W28). The foundations of the walls were set on clay soil. It seems that Walls 4 and 28 delimited the building from the south and east because no architectural remains were discovered on their exterior side. The interior walls (6, 18, 20; width 0.8 m) partitioned the building into three spaces of different sizes: an eastern space between Walls 6 and 28 (width 2.5 m); a middle space between Walls 6 and 20 (width c. 1.2 m) and a western space between Walls 20 and 18 (width 0.8 m). The few recovered potsherds were mostly body fragments, insufficient for dating this phase.
At some point in time, another wall (W2; Fig. 3: Section 2-2) was adjoined to the southern side of W4. Its foundations penetrated the ground to a depth double that of W4 and were founded on basalt boulders that were tossed into the foundation trench. It seems that W2 was meant to support W4, which began to tilt northward on the slope of the hill (Fig. 4).
The Second Phase. Changes were made to the building’s interior. Wall 20 was canceled and a new wall (W14; Fig. 5), preserved a single course high, was built on top of it. At the northern end of W14 was an opening that led to the narrow space between it and W6, which paralleled it on the east. Wall 14 and the upper course of W6 were built of large soft nari ashlars that were arranged alternately on their narrow and bottom sides (Fig. 6). A rectangular installation (L15; Fig. 7), whose walls consisted of a row of basalt fieldstones, was built in the narrow space between the walls, close to W6; the function of the installation is unclear. Wall 18 was also canceled and a tamped earth floor (L23; not marked on plan) was placed on top of it, abutting the western side of W14. Floor 23 was covered with a layer of soil (L12; not marked on plan; Fig. 8) that had burnt marks and pale pink mud-brick material and contained fragments of pottery vessels, including a bowl (Fig. 9:1), cooking pots (Fig. 9:2, 3), jars (Fig. 9:4–8), a jug (Fig. 9:9) and a juglet (Fig. 9:10) that dated to the end of the Hellenistic period. Sections of a floor built of basalt flagstones were found on both sides of Floor 23; one section (L13; Fig. 10) was located south of Floor 23, close to the northern side of W4, and the other (L16) was north and c. 2 m from the first section. A finely crafted basalt bowl (Fig. 11:1) and a fragment of a small footed-basalt bowl (Fig. 11:2) were found on the northern floor section. It is not clear when the stone pavement was installed, and whether it was connected to Floor 23 or canceled it. Floors 16 and 23 were found sunken and inclined to the east (Fig. 12).
Another section of a stone floor (L26; Fig. 13), sunken and slanting eastward, was discovered next to W28; a few potsherds were found above it. Since this floor resembled Floors 13 and 16, it was dated to the same construction phase. Both Walls 6 and 28 were also found inclined to the east. The floors and the walls slanting eastward were covered with building stone collapse (L7) that had fallen from west to east. These stones were soft chalk, whereas the walls’ foundation consisted of basalt stones. The settling of the floors and inclination of the walls to the east probably indicates that the building was destroyed by a massive earthquake.
 
The building was probably located at the southern end of the Tel Bet Gan settlement. The size of the structure and thickness of its walls indicate it was large and massive; whether it was used for defense or agricultural purposes is not clear. The destruction of the building can probably be attributed to the earthquake that struck the country in the year 64 BCE.
