The Acueducto de los Milagros (English: Miraculous Aqueduct) is the ruins of a Roman aqueduct bridge, part of the aqueduct built to supply water to the Roman colony of Emerita Augusta, today Mérida, Spain. It is thought to have been constructed during the 1st century AD, with a second phase of building (or renovations) around 300 AD. In later centuries, the inhabitants of Mérida dubbed it the "Miraculous Aqueduct" for the awe that it evoked. In the immediate vicinity, a small Roman bridge called Puente de Albarregas runs parallel to the arcades.
