Those who live do not forget all the guerrillas, linking loyal support points of the resistance in their fight for peace, freedom, and a more humane and just world. This guerrilla struggle in Asturias lasted for 15 years, from October 21, 1937, to October 13, 1952.

Pola de Lena is a town steeped in industrial history. It is strategically located at the entrance to Asturias via the highway from León and is an important commercial hub. It is also perfectly situated for starting cycling routes in the surrounding mountains.
