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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
