Dara Dam

Associated with the frontier city of Dara and dated to around 560 CE, this late Roman/Byzantine dam is famous because Procopius described it as crescent-shaped, making it the earliest textual explanation of arch-dam behavior. Modern fieldwork has raised doubts about whether the surviving remains were truly [an arch dam]((https://en.wikipedia.org/wiki/Dara_Dam)) or instead a gravity dam, so the site is notable both for its engineering history and for the unresolved interpretation. It remains a rare pre-modern large dam site tied directly to Justinian I's building program.
