The Delikkemer Aqueduct, located near Patara in Fethiye, Türkiye, exemplifies the remarkable engineering capabilities of the ancient world. Constructed during the rule of Emperor Claudius from 41 to 54 CE and subsequently restored during the reign of Emperor Vespasian from 69 to 79 CE, this aqueduct sourced water from a spring approximately 700 meters above sea level, transporting it to the city situated 23 kilometers away. Currently, only a 200-meter segment remains, reaching a height of 10 meters at its apex. Notably, unlike typical aqueducts that utilize a trough-watercourse on top, this aqueduct features a stone block pipe system.
The design employs a reverse siphonic mechanism, allowing it to transport water uphill and across uneven terrain. Each stone block measures roughly 90 centimeters square and 50 centimeters in thickness, featuring a central hole with a diameter of 30 centimeters. One side of each block is shaped to contain a recess, while the opposing side has a protruding spigot. This design allows for seamless interconnection, as the spigot of one block fits snugly into the recess of the subsequent block, effectively creating a continuous conduit for water. The blocks are sealed with mortar, resulting in a large-diameter water pipe that can withstand significant pressure, thus ensuring a consistent and effective water supply to the city.
