The María Luisa colliery is one of the most emblematic and well-known coal mining operations in Asturias, in Spain. The colliery, now closed, is located in Ciañu in the municipality of Langreo.

The deposit began to be exploited in 1858 through the María Luisa coal mine, by the Unión Hullera de Santa Ana ("Santa Ana Coal Union"), with French capital.

In 1886, it was exploited by the Sociedad Unión Hullera y Metalúrgica de Asturias.

The mine was deepened in 1918, although it would have to wait until 1942, after the Spanish Civil War, for it to operate at full capacity.

In the 1940s, 17 miners died in a firedamp explosion.

In 1976, the King and Queen of Spain, Juan Carlos and Sofía, dressed in mining costumes and descended into the mine, which caused a great impact in the media of the time.

Years later, it was also visited by the then president of the government, Adolfo Suárez.

Starting in 1967, it was exploited by Hunosa due to its integration of the mining assets of the Sociedad Metalúrgica Duro-Felguera ("Duro-Felguera Metallurgical Society"), along with other coal companies in the Asturian mining basins. It remained in operation until December 31, 2016, being the last Langreo mine to close.

The exterior facilities complex is made up of two large buildings from the 1920s that respond to the classic scheme of industrial architecture. They are covered with red brick and finish the cornice with battlements, being buildings very similar to those of the La Felguera Factory (see https://en.wikipedia.org/wiki/Felguera_Factory) from the same company. Also noteworthy are the boarding pavilion and the castle, which changed their appearance a few years before the closure of the operation due to technical improvements. The laundry was demolished in 2002. Remains of the María Luisa Group's exports are also preserved in the area: a mine opening from 1897, a brick ventilation chimney from 1900, compressors and lampworks from 1936, and the mine opening on the third level of María Luisa (1950), in El Carbayal, converted into a chapel.
