The Aqueduct of the Pillars was an aqueduct located in the city of Oviedo, of which 5 arches remain today in the district of Ciudad Naranco. It was built between 1570 and 1599 under the direction of Juan de Cerecedo, although it was completed by Gonzalo de la Bárcena, chief plumber of Valladolid.

The initial construction had forty-two arches (popularly known as "pillars"), a length of 390 metres and a height of 10 metres, at a total cost of 15,500 ducats of the time1 financed by taxes on cider and wine.

It was built to supply the city with water from the Boo and Fitoria springs on Monte Naranco. Between its construction in the 16th century and 1875, it was the largest and main water distribution channel in the city until it was replaced by a system of water tanks and pressurised pipes designed by Pedro Pérez de la Sala in 1864.

Of the aqueduct, only five pillars remain as a tribute and a reminder of what that aqueduct was, as in 1915 the rest were demolished to facilitate the widening of the city, its reorganisation and the construction of new railway lines. These five arches were restored in 2006 at a cost of some 48,000 euros.

It was declared a Historic-Artistic Monument on 26 November 1915.
