The Basque Country has the most politically charged urbex in Spain — the Lemoiz nuclear plant that never produced a kilowatt of electricity because ETA killed its engineers and the anti-nuclear movement made its opening impossible, the blast furnaces and shipyards of the Nervión Left Bank that the 1980s industrial reconversion closed within a few years, and the Hurtado de Amézaga Palace in Güeñes, an unfinished 18th-century baroque mansion that legend calls "the witches’ palace." Discover the 5 best abandoned places in the Basque Country, selected from our Urbex Map Spain — 600+ GPS locations across Spain.
Why the Basque Country Is an Exceptional Urbex Destination
The Basque Country concentrates three unique types of abandonment within its territory: the heavy industrial heritage from the 1980s reconversion — the blast furnaces, shipyards, and industrial flour mills of the Nervión Left Bank — the nuclear heritage of Lemoiz, unique in Western Europe, and the noble heritage of palaces and castles abandoned since the 18th century. The Cantabrian fog and the humid Basque vegetation create atmospheres of accelerated decay that Mediterranean urbex cannot reproduce.
1. Lemoiz Nuclear Power Plant – Lemoiz, Bizkaia — The Nuclear Plant That Never Worked, Stopped by ETA and the Anti-Nuclear Movement, the Most Spectacular Nuclear Abandonment in Western Europe (Known Place)
The Lemoiz Nuclear Power Plant, perched between cliffs on the Biscay coast, is the most politically charged abandonment in the Basque Country — built between 1972 and the 1980s, it never produced a single kilowatt. Its eroded walls still seem to resonate with the history of a turbulent chapter in Euskadi’s past: the ETA attacks that killed two chief engineers, the anti-nuclear movement that mobilized tens of thousands of Basques, and the 1983 nuclear moratorium that left it permanently halted. Since 1984, the group of buildings has not been used for any productive activity; the Basque Government is considering converting it into an aquaculture center. Owned by Iberdrola — photograph it from the outside with views of the Cantabrian Sea. Widely documented by the Basque press as Euskadi’s most emblematic abandonment.

2. Hurtado de Amézaga Palace – Güeñes, Bizkaia — Unfinished 18th-Century Baroque Small Palace, the "Witches' Palace," Covered in Ivy and Fog (Known Place)
The Hurtado de Amézaga Palace in Güeñes is one of the most mysterious and photogenically powerful abandonments in the Basque Country — an 18th-century baroque small palace that was never finished after the death of its promoter Baltasar Hurtado de Amézaga in 1720. Lost among the fog and intertwined branches of the Bizkaia forest, the palace abandoned since the 18th century is home to ivy and shadows. The legends that have emerged about the mystery of its abandonment have given it the nickname "the witches' palace." Its ruins are covered with vegetation and exposed to the elements without any legal protection. Documented by Onda Vasca as one of the eight places with the most secrets in Euskal Herria.

3. Portilla Castle – Álava — Medieval Castle on the Hilltop, Walls Merging with the Rock, Valley Views, Interior Álava (Known Place)
The Portilla Castle in the interior of Álava retains an air of invulnerability despite being a medieval ruin — atop the hill where the walls merge with the rock, the view of the valley is breathtaking. The bare walls rise like eternal guardians of ancient secrets. Every stone seems to whisper battles, conquests, and betrayals, and the echo of voices bounces between the slopes as if the fortress wants to respond, reluctant to let its memory die. Documented by Onda Vasca and Deia as one of the eight places with the most secrets in Euskal Herria — one of the most photogenic medieval castle ruins in the entire Basque Country.

4. Grandes Molinos Vascos Flour Mill – Zorroza, Bilbao — 1925 Industrial Building, Cultural Interest Asset, Collapsed Roof, Basque Regionalist Style (Exclusively on Our Map)
The old Grandes Molinos Vascos Flour Mill in Zorroza (Bilbao) is one of the most unique industrial buildings in Basque heritage — built in 1925 with a design by architect Federico de Ugalde y Echevarría in Basque regionalist style, it was declared a Cultural Interest Asset in 2009. However, its structure has suffered severe damage: the roof has collapsed and the building shows clear signs of deterioration. The transfer of the movable heritage collection to Orconera in Barakaldo has left it without current use, with an uncertain future despite legal protection. A building whose Basque regionalist architecture is so specific and photogenically powerful that heritage protection has not prevented accelerated deterioration. GPS coordinates available on our Urbex Spain Map.
5. Piérola Monastery – Inner Álava — Monastery Ruins in the Forest, Tower Pointing to the Sky, Vegetation Taking Over the Site (Off the Radar — Only on Our Map)
Inside Álava, the Piérola monastery preserves part of its walls and its tower, which points to the sky with a melancholic elegance. Light filters through the nonexistent roof, casting sliding shadows over moss-covered stones, as if nature had decided to protect it with its own green roof. Amid the vegetation that has taken over the site, the monastery is a perfect example of how abandonment in the Basque Country does not destroy — it transforms. Moss, ivy, and ferns are the new cloister. Find it on our map — with access rating and condition report.
Safety Tips
- Lemoiz: private property of Iberdrola with surveillance — never attempt to enter; the view from the coast and access via the coastal path is completely legal and photogenically sufficient
- Buildings with collapsed roofs: the Flour Mill and Amézaga Palace have structures in critical condition — limit exploration to the exterior and clearly consolidated areas only
- Never explore alone — always bring at least one other person and share your location
The urbex code: "Take nothing but photographs, leave nothing but footprints."
❓ Frequently Asked Questions
What is the most famous abandoned place in the Basque Country?
The Lemoiz Nuclear Power Plant — the most controversial energy project in Basque history, halted by the combination of the anti-nuclear movement and ETA attacks, which turned an almost finished plant into the Basque Country’s most politically charged industrial abandonment and one of the most spectacular in Western Europe.
Why are there so many industrial abandonments in the Basque Country?
The Left Bank of the Nervión was for a century the industrial heart of Spain — the blast furnaces of Sestao and Barakaldo, the shipyards of Bilbao and Euskalduna, the flour mills and factories along the estuary. The industrial restructuring of the 1980s closed all this productive fabric within a few years, leaving large-scale buildings of notable architectural quality in progressive abandonment. The speed of economic change left no time to plan the repurposing of the buildings.
What really happened to the Lemoiz Nuclear Power Plant?
Lemoiz was authorized in 1972 and built by Iberdrola (then Iberduero) with two pressurized water reactors. Opposition to the project was massive: the Basque anti-nuclear movement mobilized tens of thousands of people; ETA carried out several attacks including the assassination of two chief engineers in 1981. The socialist government decreed a nuclear moratorium in 1983 and the plant was officially shut down without ever generating a single kilowatt. The Basque Government is currently studying its conversion into an aquaculture center.
