About
About Shushtar Band-e Kaisar — Roman Bridge-Dam Caesar's Dam
500-m Roman arch bridge-dam (Band-e Kaisar, Caesar's Dam) on the Karun at Shushtar, core of UNESCO Shushtar Historical Hydraulic System (1315, 2009) 240 ha, 32.05,48.85. Built c.260 CE by captured Emperor Valerian's Roman legionnaires after Edessa for Shapur I, 44 arches spanning Karun with sluice regulation diverting Gargar artificial canal to 40 cliff water mills, orchards and weirs (Band-e Mizan, Band-e Shadirwan Salasel Castle) — Sassanian hydraulic capital reusing Roman vaulting. Paradigm of Iranian qanat to integrated system evolution Darius–Sassanid. Unlike aflaj qanats, Shushtar is river bridge-dam with Roman arch technology transfer. Still partly standing with 30 arches.
Why it mattersOnly Roman bridge-dam in Iran documenting capture-technology transfer (Valerian legion) and Sassanian hydraulic integration.
