La Mina do Salgueiro, situada en San Tirso de Abres (Asturias), fue una importante explotación de hierro con orígenes que podrían remontarse a época romana. Ubicada en la zona de San Salvador, conserva varias galerías excavadas en la roca, algunas con evidencias de trabajos tanto antiguos como industriales modernos. La mina formó parte del sistema minero del occidente asturiano, vinculado al transporte de mineral por el antiguo ferrocarril Villaodrid–Ribadeo.
Aunque cerró definitivamente en 2018, sigue siendo un punto de referencia del patrimonio minero de la comarca. Sus restos forman parte del paisaje cultural del valle del Eo, junto a castros como el de As Croas de Eilale, con los que probablemente mantuvo relación funcional. Hoy, la mina permanece cerrada al público, pero su historia perdura a través de rutas de senderismo y el recuerdo de quienes trabajaron en sus galerías.
There are remains in the Oscos region that tell us that mining was an activity that was developed in the area since prehistoric times. Before the conquest of the Romans, the inhabitants of this region were already looking for gold nuggets in the river placers. But it was after the arrival of the Romans that this industry was boosted. In the Flavian period, at the beginning of the first century A.D., a first golden age was experienced. The castros (fortified settlements) resurged as a result of the exploitations and the landscape was dotted with small industries of which there are still remains such as: forges, function furnaces and samples of the technology that was used for the exploitation of the deposit.
The house where Antonio Raimundo Ibáñez, Marquis of Sargadelos (1749-1809) was born is now an exhibition space dedicated to the life and work of this industrial and enlightened merchant, who in the late 18th century built in Sargadelos (Cervo, Lugo) one of the first cast-iron foundry and earthenware factories in Spain.
Through different media (audiovisual, photographic and computer) we can learn about the Eo River, the different species that inhabit it or the relationship of man with the river; how humans have taken advantage of the wealth offered by its waters and, above all, the importance that fishing has had in the area.
Recently, the Town Council of Villanueva de Oscos, with the collaboration of the Principality of Asturias, has recovered and rehabilitated the mines of this municipality.
The Casa del Agua de Bres, Taramundi, was created with the aim of making known the relationship between cultures and the dynamics of water throughout history. In this installation water is conceived, on the one hand, as a living substance capable of developing a force that men have been using throughout history to perform tasks that require power and routine work.
