UNESCO designated this "a masterpiece of creative genius" — one of only a handful of sites to receive this highest classification. The system comprises 13 integrated dams, bridges, canals, and water mills on the Karun River, functioning as a single hydraulic computer. Band-e Kaisar (Caesar's Dam) is the oldest known structure combining bridge and irrigation functions — built using Roman prisoners of war under Sasanian direction, fusing two engineering traditions. Hand-carved tunnels redirect the river through underground channels, powering cascading waterfalls that drive grain mills. The system served irrigation, urban water supply, fish farming, and milling simultaneously — a 1,700-year-old integrated infrastructure network that still functions today.
