Bilbao, the largest city in Spain's Basque Country, has undergone a remarkable transformation over the past few decades. Once an industrial hub, the city has redefined itself as a center for culture, innovation, and urban regeneration. This evolution has been partly driven by architecture, which plays a central role in shaping Bilbao's identity. From contemporary landmarks to thoughtfully repurposed spaces, the city's built environment reflects a careful balance between honoring its industrial heritage and embracing modernity.
