The Acueducto de los Milagros (Aqueduct of the Miracles) is a Roman aqueduct in Mérida, Spain. It was built during the first century AD to supply water from the Proserpina Dam to the ancient Roman colony of Emerita Augusta. After the fall of the Roman Empire, the aqueduct fell into decay and today it is in ruins with only a relatively small section of the aqueduct bridge standing. The Archaeological Ensemble of Mérida, including the aqueduct, was declared a UNESCO World Heritage Site in 1993.
Only a relatively small stretch of the aqueduct still stands, consisting of 38 arched pillars standing 25 metres high along a course of some 830 metres. It is constructed from opus mixtum – granite ashlar blocks interspersed with red brick – utilising a double arcade arrangement. The structure originally brought water to the city from a reservoir called the Proserpina Dam, fed by a stream called Las Pardillas, around 5 km to the north-west of Mérida.
It is thought to have been constructed during the 1st century AD, with a second phase of building (or renovations) around 300 AD. The aqueduct is preserved as part of the Archaeological Ensemble of Mérida, a UNESCO World Heritage Site.
In the immediate vicinity, a small Roman bridge called Puente de Albarregas runs parallel to the arcades.
References:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
