Proserpina Dam

The Proserpina Dam is a Roman gravity dam built to supply water to the Roman colonia of Emerita Augusta –present-day Mérida, Spain–, capital of the Roman province of Lusitania. It was built in the 1st–2nd century AD as part of the infrastructure which supplied water to the city through the aqueduct of the Miracles. After the fall of the Roman Empire, the aqueduct fell into decay, but the earth dam with retaining wall is still in use.^[1]
