At Amberd, a constant water supply was crucial for its inhabitants. The fortress' primary viaduct was a terra cotta pipeline that had been laid from the fortress to dammed reservoirs which collected sources of spring water from higher elevations and melting snow. In the event that the fortress was under attack, it was likely that the pipeline would be destroyed. Therefore, another more secret water supply would need to ensure a constant flow of water to its inhabitants to keep them from dying from thirst. A covered passageway that led from the fortifications along a steep pathway descending down a cleft in the rocks to the Arkashen River performed such a task.
