Esparragalejo Dam

The Esparragalejo Dam was a Roman multiple arch buttress dam located in Esparragalejo, Badajoz province, Extremadura, Spain. Built in the 1st century AD during the early Roman Empire, it is the earliest known multiple arch dam in the world, representing a pioneering engineering achievement in dam construction history. The structure utilized a series of arches to distribute water pressure, a revolutionary technique that would not be widely replicated until many centuries later. This dam exemplifies Roman hydraulic engineering expertise and their ability to construct complex water management infrastructure in the Iberian Peninsula. [1]
