The Acueducto de los Milagros, located in Mérida, Spain, is a Roman aqueduct dating back to the first century AD. It was built to supply water from the Proserpina Dam to the ancient Roman colony of Emerita Augusta. Today, only a small section of the aqueduct bridge remains standing, with 38 arched pillars reaching 25 meters high. The locals even nicknamed it the "Aqueduct of the Miracles" because of its awe-inspiring presence. This historical site is part of the UNESCO World Heritage Site of the Archaeological Ensemble of Mérida.
