The aqueducts appearing in the west on the way to Sirince along the Cirkince mountain-pass, were built during the Byzantine Era to carry water to the Church of St Jean. These endless aqueducts parallel the highway from Belevi and circle around the slopes of the mountains, passing over the valley at the Sirince mountain-pass. The traces of an aqueduct found at the southern and western stairs of the Belevi Tomb is thought to be part of the Pranga Watershad.
