The Explorations at Jerusalem: voussoir of Robinson's Arch fallen through the arch of tunnel below, 1869. 'A canal or aqueduct, 12 ft. deep and about 6 ft. wide, running from north to south along the valley, is cut in the rock and roofed with masonry so as to form a kind of tunnel. One of the largest voussoirs [vousoirs, or wedge-shaped stones] of the lofty bridge, falling from above, has broken through the roof of the aqueduct tunnel, and now rests upon the solid rock of its sides. This aqueduct leads to an oval cistern about 30 ft. lower down the valley, which communicates with others beyond it'. From "Illustrated London News", 1869.
