Aqueduct de los Milagros, Spain
The Acueducto de los Milagros, which translates into the fantastically named Miraculous Aqueduct in English was built in the ancient Roman era. It was used to supply water to the residents of the Emerita Augusta colony below, which is now the town of Mérida in Badajoz in Spain.
Made using the materials the construction workers had in plentiful supply at the time, namely brick, granite, masonry and natural stone, it’s a stunning construction. Standing at around 25 metres high, it’s made up of three rows of arches, one on top of the other. In its heyday, it would’ve had, now long forgotten, basins that would’ve distributed the water to residents.
Now a UNESCO World Heritage Site, the Aqueduct de los Milagros bridge is a popular tourist destination with visitors flocking to the area to see the stunning fields and green spaces that surround it.
We suspect that many visitors stand back and admire this bridge (which is no longer used for pedestrians) and marvel at the miraculous-ness of its structure and engineering, and the fact that it was completely made by the hands of humans. No data is available to tell us quite how dangerous a build this was, but we suspect it was pretty dangerous.
