Unit 1
This unit extended across a relatively small area (Figs. 1–3). The quarrying at the southern end was deep and five steps were discerned (height 0.5–2.0 m; Fig. 2: Section 1-1). Numerous quarrying and severance channels (length 1.5–2.0 m, width 0.1–0.2 m, depth 0.15–0.50 m) were exposed on the floors of the quarry, which facilitated the reconstruction of the stones that had been removed from the unit and their dimensions (max. dimensions c. 1.1 × 1.5 m).
A square rock-hewn installation (L560; 1.5 × 1.5 m) was exposed between Unit 1 and a burial cave to its west; the cave was not excavated. Three of the installation’s sides were well preserved (height 1.5–2.0 m) and its northern side (preserved height 0.45 m) was cut by the quarry. Two triangular recesses (height c. 10 cm, depth c. 4.5 cm), probably used for descent into the installation, were exposed in the southern and western sides, c. 0.8 m above the floor. A circular depression (L561; diam. 0.2 m, depth 0.15 m) was exposed on the floor of the installation in the south. Sections of gray plaster remained on the floor and on the sides (Fig. 4). The installation was probably the collecting vat of a winepress that predated the quarry and the rest of its components were destroyed by the rock-cutting activity in the area.   
Unit 2
The eastern boundary (min. length c. 10 m) of the unit was exposed northeast of the burial cave; most of the unit was situated beyond the limits of the excavation. Four–five quarrying steps (height 0.5–1.0 m) that faced north and west (Fig. 5) and quarrying channels (maxi. depth 0.5 m) were revealed.
Remains of a built tomb (L567) that was not excavated were discovered in the north, below the quarrying steps. The tomb was covered with soil fill and quarrying debris, which contained fragments of pottery vessels dating to the Roman period.
Unit 3
The unit was hewn around a prominent bedrock knoll, whence rock-cut steps descended to the north and south (height c. 1.5 m; Figs. 2: Section 2-2; 6). The northern border of the unit was located beyond the limits of the excavation.
An in-situ stone, partially detached from the bedrock (L562; length 1.5 m, width 0.8 m, height 0.5 m; Fig. 7), was exposed in the north. Apart from this stone, no other stones remained in the quarry.
Unit 4
The bottom level of the unit, which contained quarrying debris and small stones (Fig. 2: Section 4-4), was mostly exposed. Relatively shallow severance channels (up to 0.15 m deep; Fig. 8) remained on the floor. The border of the unit (min. length c. 12 m) was exposed on the southwestern side where the largest quarrying steps, which faced north, were hewn (max. height 2 m; Figs. 2: Section 3-3; 8).
Two broken stone columns were discovered in a layer of stone chips that covered the floor next to the steps; fissures in the columns caused them to break at the time of their quarrying (Fig. 9).
Fragments of pottery vessels dating to the Roman period were found on the bedrock layer at the bottom of the quarry and between the soil fill and the stone chip debris. Potsherds dating to the Byzantine period were found in the layers of fill closest to the surface, which accumulated on the ancient fill. These potsherds probably derived from buildings or installations outside the excavation area.
The exposed quarry was part of an extensive region of quarries, spread across the hard limestone outcrops north of the Jerusalem city walls. These quarries supplied building stones to the northern neighborhoods of the city in the Second Temple period and later.
