Bilbao is known for its vibrant mix of modern art, rich Basque culture, and scenic landscapes. Yet, nestled among the city’s attractions are remnants of its industrial past—sites that tell the story of Bilbao’s rise as a powerhouse in iron, shipbuilding, and trade. For travellers who want to step off the beaten path, here are five hidden industrial gems worth exploring.
1. Remnants of a blast furnace
Once the largest steel company in Spain, Altos Hornos de Vizcaya (AHV) was the heartbeat of Bilbao’s industrial era. Founded in 1902, AHV shaped the city’s economy and social landscape for much of the 20th century. Although production halted in the 1990s, you can still explore the old plant site in Sestao. Walk among the remnants of a blast furnace.
2. Concrete grain mill
The Grandes Molinos Vascos is an architectural wonder just a short drive from central Bilbao. Built in the 1920s as a grain mill, the building’s unique design by architect Manuel Ignacio Galíndez reflects a fascinating combination of industrial functionality and artistic design.
3. Repurposed shipyard
The Euskalduna shipyard was at the heart of Bilbao’s shipbuilding industry for over a century. While shipbuilding operations ceased in the 1980s, the site was reimagined as the Euskalduna Conference Centre and Concert Hall. This award-winning architectural space celebrates its roots by preserving elements of the original shipyard, including a powerful crane.
4. Iron ore mining
Just outside of Bilbao lies the Mina San Luis, an old iron ore mine in Trapagaran. This site played a crucial role in Bilbao’s steel production, providing the raw material that fueled the city’s booming industry. Today, visitors can explore the remnants of mining infrastructure and take a funicular ride up to the La Arboleda mining village, where you can enjoy sweeping views of the valley and get a glimpse of the miners’ way of life.
5. World's oldest transporter bridge
This engineering marvel, completed in 1893, holds the title of the world’s oldest transporter bridge. Designed by Alberto Palacio, a disciple of Gustave Eiffel, the Vizcaya Bridge still operates today, ferrying pedestrians and cars across the Nervion River. The bridge’s remarkable iron structure and intricate design have earned it UNESCO World Heritage status. Visitors can cross the bridge via the transporter gondola or take an elevator to the top for panoramic views of Bilbao’s industrial and natural landscapes.
Each of these locations reveals a different chapter of Bilbao’s industrial heritage. They’re a reminder of the city’s transformation from a steel and shipbuilding giant to the modern cultural hub it is today. So next time you’re in Bilbao or in the Basque Country, take a detour to these hidden gems—you’ll leave with a richer appreciation of the region's storied past.
