Barcelona's Duplicate Image Crisis: The Key Decisions That Will Shape the City's Visual Identity

Barcelona's Ajuntament faces a reckoning over its digital image infrastructure. Across the city's official tourism portals, municipal archive systems, and the Barcelona Turisme platform, cataloguers have identified a sprawling backlog of duplicate and near-duplicate photographs — thousands of redundant images of the same sites, from the Sagrada Família's nave to the Barceloneta beachfront, clogging databases and sending inconsistent visual messages to the 26 million tourists who visited the city in 2024.

The problem is not cosmetic. Barcelona's visual identity is a commercial and political asset, and how the city manages its photographic record feeds directly into the broader debate about overtourism, authenticity, and who controls the city's image. Mayor Jaume Collboni has made the management of tourism infrastructure — including the expanded tourist tax introduced in 2024, which raised the per-night surcharge for cruise passengers to €7 — a centrepiece of his administration. Sloppy digital asset management undercuts that ambition at the most basic level.

The immediate trigger is a modernisation project underway at the Institut de Cultura de Barcelona, which oversees the city's cultural data systems. Technicians working on the integration of legacy photographic databases into a unified content management platform discovered that in some landmark categories — particularly images of the Passeig de Gràcia and the Gothic Quarter — duplication rates exceed 60 percent. That figure comes from internal project documentation circulated among municipal technology staff in June 2026. The Barcelona Supercomputing Center at the Polytechnic University campus on Jordi Girona street has been consulted on AI-assisted deduplication tools, a process that carries its own editorial risks.

The Decisions That Cannot Be Delayed

Three choices now sit in front of the Ajuntament's digital governance team. First: which images get retired and which survive? That sounds administrative, but it is also curatorial. A photograph of the Mercat de la Boqueria taken before the 2023 vendor restructuring tells a different story than one taken after. Deleting the older version for tidiness erases a document of change. The Institut Municipal d'Informàtica, which manages the city's data systems from its offices on Carrer de Tànger in the 22@ district, has been asked to draft a retention protocol by September 2026.

Second: who owns the canonical image? Barcelona Turisme, the semi-public body that manages international promotion, operates its image library partly independently of the Ajuntament's own archive. The two systems have grown apart over years of parallel development. Reconciling them requires not just a technical merge but a political agreement about which institution holds editorial authority over official city imagery. That negotiation has no firm deadline yet.

Third: what role should artificial intelligence play in deciding which duplicates to delete? The Barcelona Supercomputing Center's deduplication tools can flag near-identical images with high accuracy, but edge cases — photographs taken seconds apart during the same shoot — require human judgment. Automating those decisions without oversight risks discarding images that have specific legal or archival value, particularly photographs used as evidence in planning disputes around areas like the Eixample's superblock programme.

What Comes Next

The Institut de Cultura de Barcelona is expected to publish a public consultation document on digital asset governance before the end of summer 2026. That process will give cultural organisations, photographers' associations including the Col·legi de Llicenciats en Belles Arts i Professors de Dibuix de Catalunya, and civic groups a formal opportunity to weigh in before any mass deletion occurs.

For now, the practical advice for anyone — journalists, researchers, marketing agencies — working with official Barcelona imagery is straightforward: treat the current municipal databases as provisional. Cross-reference any photograph obtained from the Ajuntament's public portal against Barcelona Turisme's separate library before publication. Discrepancies in caption data, geotags, and licensing terms are common.

The deduplication project is scheduled to reach its first operational phase in the fourth quarter of 2026. Whether the city's institutions can agree on governance before the technical work is complete is the question that matters most. Getting the software right is the easy part.
