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.
The history of Villanueva de Oscos is closely linked to the Monastery of Santa María, at the entrance of the capital of the council. This Monastery, considered one of the great jewels of Asturian heritage and classified as a Historic-Artistic Monument, was born Romanesque and grew Baroque.
The town of Vegadeo has the peculiarity of being crossed by two rivers: the Monjardín and the Suarón, which have twelve bridges that cross them (six each). Taking advantage of this circumstance, the idea was that visitors to Vegadeo could get to know the town center by crossing these bridges, and enriching the visit with a sculpture on each of them.
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.
This museum was created to show the great variety of hydraulic and hand-operated mills that were used throughout history and in different parts of the world to grind cereals.
