Los Milagros Aqueduct, Merida, Spain. The Acueducto de los Milagros ('Miraculous Aqueduct') is a ruined Roman aqueduct in Merida, Spain, formerly the Roman colony of Emerita Augusta. Only a relatively small stretch of the aqueduct still stands, consisting of 38 arched pillars standing 25 metres (82 ft) high along a course of some 830 metres (2,700 ft). It is constructed from granite ashlar blocks interspersed with red brick and utilises a double arcade arrangement. The structure originally brought water to the city from an artificial lake, called the Lago de Proserpina, supplied by the river Aberregas around 5 km (3 miles) to the north-west of Merida. It is thought to have been constructed during the 1st century AD, with a second phase of building (or renovations) around 300 AD.
