Langreo

Langreo is a municipality in the autonomous community of the Principality of Asturias, Spain. It is located in the Nalón Valley in central Asturias and forms part of the Nalón comarca. The municipality includes the urban centers of Sama de Langreo and La Felguera, historical coal mining towns that grew together during the industrial era. With around 40,000 inhabitants, Langreo lies roughly 20-25 kilometers north of Oviedo and to the west of Gijón.

Langreo developed from coal mining and metalworking in the 19th century, becoming an important industrial hub in Asturias. The growth of mines along the Nalón basin led to rapid urbanization and the emergence of the districts of Sama, La Felguera and El Entrego. The decline of coal production in the late 20th century prompted economic restructuring and a shift toward services and light industry.

Today Langreo maintains its industrial heritage and has diversified its economy. The area hosts cultural and recreational facilities and preserves its mining legacy, including the Museo de la Minería y de la Industria in El Entrego. The municipality is also home to Unión Popular Langreo (UP Langreo), a football club with historic ties to the local communities.

Langreo is served by road connections to Oviedo and Gijón and lies along routes that link the Nalón valley with western Asturias. The Nalón River and the surrounding hills shape its landscape, offering viewpoints and walking routes for residents and visitors alike.
