Zerain is a small village in the Basque Country known as the “Iron Mountain” due to its rich industrial heritage related to iron mining.
In this text, I share my impressions of the visit and provide a detailed view of what to expect when visiting this iconic Basque site.
However, readers should be warned that Zerain is a place that exceeded all expectations!
There is something simply irresistible about the combination of industrial ambiance and pristine nature that I didn’t think possible.
For me, the Iron Mountain was one of the great revelations of the Basque Country! However, Zerain has more to offer beyond its mining past.
Therefore, I also included suggestions on what to do and visit in the village center, as well as a restaurant recommendation, so you can plan your itinerary.
Continue reading to the end, check out the photos, and discover what makes this place such a special and unforgettable destination.









Zerain, the Iron Mountain (Aizpea Furnaces)
Zerain, affectionately nicknamed the “Iron Mountain,” has played a crucial role in the region’s economy for centuries.
Iron mining in Zerain dates back to the medieval period, and the area was a significant production center until the 19th century.
The importance of the iron extracted in Zerain cannot be overstated, as this resource was vital for the local industry and for the manufacturing of weapons and tools.
The mines, which once were a part of village life, are now a place of discovery for curious visitors like myself.
During a visit to the Aizpea Furnaces, you can explore the ancient furnaces as well as the channels used for iron smelting.










The Iron Mountain Experience: A Journey into the Past
The experience at the Aizpea Furnaces begins with an interactive visit to the main building, where explanations about the region’s mining history are provided.
Next, you follow a trail that leads to the old iron mines, where you can get a close look at the remnants of mining activity: the mines and the furnaces.
The old mines, now silent, are a haunting place. It is hard to imagine what life was like for the miners inside these dark, poorly ventilated tunnels. It was undoubtedly hard work.
You can explore part of the underground galleries with the help of specialized guides, even though they are not fully accessible, and it is well worth the effort.
Additionally, I found it very interesting to see how the old lime kilns and the channels used for smelting iron are still well-preserved.
These remnants of the past reveal the ingenuity of the techniques used at the time, as these ancient furnaces were used to transform iron into ingots.
The furnaces were fed from the top; rocks containing ore were placed at the top of the furnace, which was then ignited.
The molten iron was extracted from the mouth of the furnace, that is, from the bottom.
It was a continuous job of adding rocks, controlling the combustion, and removing the molten metal.

Around Zerain: What to Do and See (Beyond Visiting the Iron Mountain)


Although the Aizpea Furnaces are truly something out of the ordinary, the center of Zerain is also worth exploring.
Thus, my visit to Zerain included a walk through the town center, with a stop at the Zerain Ethnographic Museum.
This museum is excellent for understanding traditional Basque life, as it features exhibits on rural life, craftsmanship, and local traditions.
I really enjoyed this exhibition.




Additionally, I had the opportunity to have lunch at the Ostatu de Zerain Restaurant and I highly recommend it!
One of the unique features of this restaurant is that the room where we had lunch was the former prison of Zerain.
You can really see that the light was quite limited.
