Barcelona on the brink of collapse: the Catalan capital becomes the planet's most tourist-saturated city

With 15 million visitors in 2024, it has been crowned by Nomad eSIM’s report as the most crowded city in the world: more than 201,700 tourists per square kilometre, surpassing giants such as Dubai, Bangkok and Paris.

The picture is overwhelming. For every 100 Barcelonans, there are 916 tourists. The city receives more travellers each year than Australia and Brazil combined. What began as an economic engine has become a phenomenon that erodes everyday life: unaffordable rents, transport at breaking point, neighbourhoods where Catalan has been replaced by menus in five languages.

The banners do not lie: “This is not a theme park,” reads one on the façades of Ciutat Vella. Public discontent is escalating. In neighbourhoods such as Gràcia, Raval and Poble-sec, the community fabric is unravelling in the face of the relentless expansion of tourist accommodation. Even cruise ships, with their daily waves of thousands of passengers, have come under scrutiny.

The City Council has tried to put on the brakes: fewer licences, higher levies, bans on new hotels. But the sense of urgency is growing. Barcelona stands at an urban precipice where the question is no longer how many tourists it can accommodate, but how many more it can withstand without losing itself.
