There is a moment on the road from Bilbao Airport into the city when the landscape changes. One minute you are moving through soft green hills, damp and wooded, more Connemara than Costa del Sol, the next you’re descending through tunnels and sweeping viaducts into a dense urban bowl set out either side of a serpentine river. The city appears suddenly, dramatically, almost as though somebody pulled back a curtain.

Bilbao is a city whose DNA is shaped by geography, by geology, by necessity and by reinvention. The DNA of Cities, a collaborative platform led by Prof Greg Clark and Dr Caitlin Morrissey, attempts to decode precisely this. Why do certain cities feel instantly recognisable and emotionally coherent while others seem interchangeable? What hidden strands shape the personality, resilience and trajectory of urban places?

Over the past year, through work with City Destinations Alliance, I’ve had the privilege of hearing Greg and Caitlin unpack these questions and, perhaps more importantly, challenge destinations to stop thinking only in terms of tourism slogans and marketing campaigns. Cities, they argue, are organisms. Their future only really makes sense when viewed through the lens of their DNA.

Bilbao’s original code was hard core industrial.

Huge deposits of iron ore in the surrounding hills, combined with the convenient transport artery of the Nervión River, transformed Bilbao into one of Spain’s great industrial powerhouses during the nineteenth and twentieth centuries. Shipbuilding, steel production and heavy engineering dominated the city. Wealth flowed in. So did workers. The river became an industrial conveyor belt lined with cranes, docks and factories.

By the 1970s, however, the industrial model had collapsed. Globalisation, changing manufacturing patterns and economic decline hit Bilbao brutally hard. Unemployment soared. Pollution became overwhelming. The river that had once sustained the city became, quite literally, toxic. What had been Bilbao’s defining strength now felt like a burden, almost a curse.

And yet the extraordinary thing about Bilbao is that the city never attempted to erase this inheritance. It didn’t pretend to become Florence or Paris or Barcelona. Instead, it rewrote its future using the raw material of its past.

That, perhaps, is the central lesson of the DNA of Cities framework. Successful cities rarely succeed by imitation. They evolve authentically from what they already are.

Bilbao’s recovery was not one grand gesture but a deeply co-ordinated civic project stretching across decades and multifarious stakeholder communities. National, regional and local government aligned – magically and implausibly – behind a common ambition. Universities, port authorities, transport agencies and business leaders pulled in the same direction. Plans connected to other plans. Infrastructure connected to culture. Public realm connected to economic strategy.

The city itself became the project.

New transport infrastructure stitched the fragmented urban fabric together. Santiago Calatrava designed the airport terminal, a structure that seems permanently poised for flight. Norman Foster created a metro system whose sleek entrances still look futuristic decades later. The riverbanks were reclaimed from industry and handed back to citizens. Public spaces emerged where cranes once stood.

And then came the audacious move that changed global perceptions forever.

The decision to invite Frank Gehry to build the Guggenheim Museum Bilbao on a derelict riverside site has been analysed endlessly in urban studies circles, often reduced lazily to the so called “Bilbao Effect.” But standing beside the building itself, shimmering like a giant titanium ship caught mid-turn in the river light, you realise the museum only worked because the groundwork had already been laid.

The Guggenheim did not save Bilbao on its own.

It became the symbol of a city already saving itself.

And perhaps what makes Bilbao especially compelling today is that it still feels grounded, still human scale, still somehow affordable despite its global reputation.

This is not a polished museum piece of a city curated exclusively for tourists. It remains deeply lived in. You notice it everywhere. In the steep residential streets climbing the hillsides. In the elevators and funiculars carrying people vertically through the urban landscape. In the old men drinking small beers beneath Palestinian flags hanging from apartment balconies. In the café prices that still feel almost miraculous compared to much of Europe.

A flat white for two euro. Albariño for four fifty. A spectacular glass of champagne in a riverside seafood bar for twelve euro. A funicular ride up the mountainside for three fifty. Entry to one of the world’s great museums for little more than the price of sandwich

Bilbao still belongs to its citizens first and that matters.

So many successful cities eventually become victims of their own success, polished smooth by global capital until their local distinctiveness disappears. Bilbao has somehow resisted this fate. Its Basque identity remains strong and visible, not in a performative way but as part of the city’s everyday texture and confidence.

Even the geography insists on authenticity.

Unlike sprawling flatland cities, Bilbao sits compressed into a steep green basin, terraces climbing upward from the river like an amphitheatre. There is very little room to expand, so the city folds in on itself. The surrounding mountains are never absent from view. Nor is the weather. Atlantic clouds roll in quickly here. Rain arrives suddenly and frequently. Light shifts constantly.

At the Guggenheim, I found myself unexpectedly moved by the work of Ruth Asawa. Her woven wire sculptures hang delicately in space like floating DNA strands, or snowflakes, or flowers, or underwater organisms. What struck me most was the contradiction at the heart of the work. Industrial wire transformed into something soft, organic and almost impossibly gentle.

Hard material becoming beauty.

Which, when you think about it, is also the story of Bilbao itself.

Asawa and her husband, architect Albert Lanier, raised six children while weaving art and family life seamlessly together. The domestic and the creative co-existed naturally. There was no hard separation between making a life and making meaning.

Again, Bilbao feels similar.

This is not a city that chose between industry and culture, between functionality and beauty, between working life and quality of life. Instead it found a way, slowly and imperfectly, to hold all of these things together.

That may ultimately be the most important insight hidden within its DNA.
