The Los Milagros Aqueduct is an incredibly well-preserved Roman water supply system in Merida, Spain.

The Los Milagros Aqueduct history

Comprised of a trio of levels of looming brick arches, the remains of the Los Milagros Aqueduct are a fantastic example of Roman engineering.

This colossal aqueduct is part of a hydraulic system that brought waters from the Proserpina Dam, also known as the Albuera Reservoir. It is popularly known as “Los Milagros” (“The Miraculous One”) because of the admiration that its state of conservation brings about in locals and visitors, especially considering the vicissitudes of time. It lives up to its popular name, as more than 800 metres of this aqueduct still stand today and some of its brick and granite support structures rise twenty-seven metres above the ground.

At the north end, where the valley of the Albarregas River starts, the construction had a type of pool to purify the water, which likewise served as a water source. As the thalweg becomes more pronounced, the height of the support piles and the number of arcades increases; all so that the hydraulic system remains suspended at the perfect height for water to flow into the city.

In ancient Roman times, the Los Milagros Aqueduct would have supplied water to Augusta Emerita, which was the capital of Roman Lusitania and which would become modern Merida.

Today, it is visible from afar and can be viewed from the roadside and surrounding fields. 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.

Together with other sites such as the Merida Roman Circus and Merida Amphitheatre, the Los Milagros Aqueduct is a UNESCO World Heritage site.
