Altos Hornos de Vizcaya

The Altos Hornos de Vizcaya complex spans across industrial grounds and features multiple furnaces that processed iron ore into steel products.

Founded in 1902, this metallurgical facility emerged from the merger of three major iron and steel companies: Altos Hornos de Bilbao, La Vizcaya, and La Iberia.

The facility transformed the social structure of Greater Bilbao by attracting thousands of workers from rural areas, leading to rapid urban development.

The strategic location near Bilbao's port enabled efficient transportation of raw materials and finished products throughout its operational period.

At its peak, the facility employed 40,000 workers, making it the largest industrial enterprise in Spain during most of the 20th century.
