The Acueducto de los Milagros ("Aqueduct of Miracles") is a 1st-century AD Roman aqueduct built to carry water from the Proserpina reservoir to the colony of Augusta Emerita (modern Merida, Spain). Its remaining stretch of 830 meters features 38 pillars standing 25 meters high, constructed with alternating courses of granite ashlar and brick bonded by opus caementicium cores. It was one of three aqueducts serving Merida. The structure is part of the Archaeological Ensemble of Merida, a UNESCO World Heritage Site.
