Joint Expedition to Caesarea

This broken portion of the high-level aqueduct and the section drawing of it show clearly that the aqueduct was built in two parts, side by side. We are looking at a vertical slice perpendicular to the length of the aqueduct. The outer lip of the right-hand (eastern) channel is broken away completely (see arrow in drawing in which it has been restored). Just below the point where this outer channel wall should be is a pointed protrusion that was part of a decorative cornice running along the length of the eastern channel. A matching cornice pointing to the left can be seen in the drawing and in the photograph in the shadow of the vertical crack separating the eastern and western channels. This cornice, now hidden by the adjacent channel on the left (west), shows that both sides of the earlier eastern channel were finished and exposed to view until the later (western) channel was added in the second century.
