Milan's Digital Archives Are Riddled With Duplicate Images — And Residents Are Paying the Price

Milan's municipal digital infrastructure is carrying a significant and largely invisible burden: tens of thousands of duplicate image files lodged across public-facing databases, civic planning portals, and the cultural archive systems that underpin everything from building permits in Porta Nuova to heritage documentation along Corso Magenta. The problem is not cosmetic. It is costing city departments storage budget, slowing application processing, and — in at least one documented case involving the Registro Immobiliare at the Catasto office on Via Larga — generating conflicting property records that have delayed residential transactions.

Why does this matter now? Milan is deep in the operational phase of the Milan-Cortina 2026 Winter Olympics preparation, with the city committed to a shared digital asset management platform connecting the Comune di Milano, Regione Lombardia, and the Milan-Cortina 2026 Foundation. That platform, intended to centralise press photography, venue documentation, and public communication assets, is only as reliable as the image libraries feeding into it. Duplicate entries — the same photograph of PalaItalia Santa Giulia appearing under three different file names, for example — do not merely waste space. They create version-control failures that can surface in public communications at the worst possible moment.

How the Problem Builds Up in a City This Active

Milan generates an extraordinary volume of institutional photography. The Triennale di Milano alone produces documentation from dozens of exhibitions per year. The Comune's urban planning directorate photographs construction-site compliance across hundreds of active sites, including the ongoing transformation of the former Expo area at Cascina Merlata. Fashion Week, held twice annually at locations including the Fiera Milano complex in Rho-Pero and venues throughout the Quadrilatero della Moda, floods press servers with near-identical images submitted by accredited photographers under different file names. Without a systematic deduplication protocol, these archives bloat rapidly.

The issue compounds in neighbourhood-level services. Citizens using the Fascicolo del Fabbricato portal — the digital building dossier system the city has been expanding since 2023 — sometimes encounter duplicate image attachments on their property files, a glitch that administrators have acknowledged requires manual review to resolve. In the Navigli district, where renovation permits have surged following the Navigli reopening project, processing backlogs have been linked in part to document-management inefficiencies, including image duplication flagged during internal audits.

What Residents Can Do, and What the City Must Fix

For ordinary Milanese, the practical consequences range from minor frustration to genuine delay. A homeowner in Isola submitting renovation documentation through the Sportello Unico Edilizia risks having an uploaded floor-plan photo duplicated automatically by the portal if the upload times out and restarts — a known bug that the Comune's digital services team has been working to patch since early 2026. The workaround, according to the portal's own help documentation, is to clear browser cache before resubmitting and to use file names that include the property cadastral code.

Businesses in the design and fashion economy face a sharper version of the same problem. Studios operating out of Tortona Design District, which hosts hundreds of accredited firms during Fuorisalone each April, maintain image portfolios submitted to multiple institutional partners simultaneously. Without industry-standard deduplication tools — software such as those used by major European cultural institutions, typically licensed at between €3,000 and €12,000 annually depending on archive size — small studios risk their work appearing inconsistently across partner platforms.

The Milan-Cortina 2026 Foundation's communications deadline for finalised venue image libraries is understood to fall before the end of August 2026, leaving just weeks for the Comune and its partners to audit and clean shared repositories. City administrators have the technical means to address this: the Agenzia per l'Italia Digitale published updated guidelines on public-sector digital asset management in March 2025, and Regione Lombardia has allocated funds under its Piano Lombardia Digitale for precisely this kind of infrastructure maintenance. The question is whether coordination across multiple institutions — each with its own IT priorities — can move fast enough. For residents waiting on permits, for archivists at the Archivio Civico Fotografico on Via Rossini, and for the Olympic project managers counting down to February, the answer matters more than it might appear.
