The Last Days and Afterlife of the San Nicolás Mine

In Asturias, Spain, coal is no longer king, and a region is being reinvented.

In 2010, the Spanish government came to an agreement with the European Union that formalized what was already a deep, generational shift in the country’s relationship to coal, a resource that had profoundly shaped the economy and culture of the northern principalities. In accordance with that agreement, Spain would shutter any remaining state-subsidized, uncompetitive coal mines by the end of 2018, thus accelerating the country’s shift toward cleaner energy and a brave new economy. Spanish coal by then was more of an industrial tradition than a major economic force, with the country importing more than 90 percent of its coal used for energy—a far cry from the industry’s heyday in the 1950s and ’60s, when it employed more than 100,000 miners across the country. By 2020, when photographer Lys Arango began documenting coal’s last chapter, that number had winnowed to fewer than three hundred, all working at the country’s last active mine.

Arango’s grandparents had settled in the northwestern region of Asturias when coal was king. Her father grew up in the town of La Felguera and eventually moved to metropolitan Madrid to raise a family. He often told his children stories of the strangely idyllic countryside of his boyhood, set against mountains and valleys permeated by the sights and sounds of coal’s extraction. To a child in Madrid, these stories had a fantastical quality. “He described a world of green mountains and narrow valleys, where the river ran black and the town awoke to the siren—the turullu— announcing the descent of workers into the Earth’s interior.”

The future of the coal industry was a political flashpoint when Arango was a journalism intern in 2012. That summer, the Asturian miners’ strike led to intense clashes with police, along with the blockage of several dozen roads and even train lines. There was, too, an outpouring of public support as thousands gathered to greet a group of more than two hundred miners who had embarked on a twenty-day march to Madrid. It was during this turbulent summer that Arango began to look for ways to document the aftershocks of coal’s absence. As with many industries, coal was more than just a resource; it embodied a culture and a political tradition. And yet its end was inevitable. The future belonged to new industries—and by extension, new ways of life.

The San Nicolás mine, located in the same Asturian basin where Arango’s father grew up, was the last to go, the last three hundred miners pushed into unpredictable futures. Arango headed there in October 2020 to document what this transition would look like, and what Asturians had to say about it, capturing the vestiges of her father’s boyhood legends. 

“At first, the project was more about the decline of the mine culture,” she says. “But after documenting this end of mining and its cultural legacy in these towns, I thought it would be interesting to cover what happens after coal. To show how the region begins its social and environmental evolution. In Asturias, they’re very proud of their mining past. Without the industry, they had no clear definition. People couldn’t find work, villages saw depopulation. But there was also this other thing happening: Some people decided to stay and redefine what life would be like in these towns after mining. So, it was fascinating to watch and capture this tension between nostalgia and possibility.”

Thais Mellado Fernández waits at the entrance to the San Nicolás mine for the elevator that will take her down to the galleries—the underground tunnels where coal is extracted. Fernández began working as a miner at the age of twenty-one under the condition of “absolute preference,” a hiring priority given to applicants with family ties to miners who were killed on the job (Fernández’s father was killed in the San Nicolás mine). Mieres, Spain, January 2022.

A locked entrance to the former washrooms of the San Nicolás mine. In mining infrastructure, these spaces often served as informal locker rooms where miners changed clothes and showered after long shifts underground. At its peak, the mine employed up to 1,500 workers; by the time this photograph was taken, only around 300 remained, and parts of the building had already been closed. Mieres, Spain, January 2022.

The new economies of these former mining villages leaned into that redefinition, transforming portions of the closed mines into museums, such as the site of Pozo Sotón, where visitors can descend into a six-hour tour of the mine itself. Other projects included converting sites into cultural and performance spaces. Some mines were flooded as part of new geothermal systems. Remarkably, thanks to a government program that has rehabilitated thousands of acres, kiwis and apples grow on land that was once the site of massive pit mines.

Plenty of risks and rewards have accompanied Spain’s commitment to renewable energy. In 2019, the government launched a program known as the “Just Transition,” which incentivized early retirement, offered job training for new skills, and provided investments in cottage industries as well as funding for environmental restoration. A less concrete, though no less profound, concern was how people shaped for generations by coal would answer a fundamental question: What’s a mining town without a mine?

“This question—Who do we become now?—it’s alive. Many people in Asturias ask it, because they’re very proud of a past they have to let go of. This absence is part of the story, and, in many ways, it speaks louder than any direct testimony. It also aligns perfectly with my visual language. So when people talk to me about what came before and what comes after—for me, I try to resist these binary narratives, because what interests me is the in-between where loss and possibility coexist.”

Former miner Oscar Iglesias and his canary at the entrance to the San Nicolás mine. For decades, miners carried canaries underground as an early warning system: The birds are far more sensitive than humans to dangerous gases. If a canary showed signs of distress or died, miners would immediately evacuate the mine. Canaries remain a powerful symbol of risk, vigilance, and memory in the Asturian mining basin.
