I will focus on the coal mines of Asturias and the north of León, I have close family who have worked their entire lives in those mines and I know the place well.

In principle I consider that they should be separated from the rest of the mining deposits in other areas of Spain that have nothing to do with the coal mines on the northern slope. I consider that they have a special relevance although they have certain similarities with the mines of the Ruhr and the UK, they are mines that are more than a hundred years old, they were the main economic engine of Francoist Spain and at the same time points of rebellion and resistance against the regime and the Franco's fascist oppression, added to the harsh working conditions that took the lives of many miners.

In 2014, the European Union made the brilliant decision to force Spain to close its mines in order to buy cheaper coal from China.

I consider that the coal mines of Asturias and León constitute an industrial heritage of historical value, not only for Spain and Europe but also for all of humanity.
