How Milan's Digital Archives Ended Up Full of the Same Image Twice — And Why It Took Years to Fix

Milan's municipal digital archive — spanning everything from planning documents filed at the Palazzo Marino to promotional assets produced for the Milan-Cortina 2026 Winter Olympics — is currently undergoing a systematic audit to identify and replace thousands of duplicate image files embedded across city-linked databases and public-facing platforms. The problem is structural, not accidental, and it took the better part of a decade to reach the point where anyone with budget authority decided it was worth fixing.

The stakes are higher here than in most European cities. Milan's economy runs on image, quite literally. Fashion week, the Salone del Mobile at the Fiera Milano complex in Rho, luxury retail along the Quadrilatero della Moda — all of it depends on precise, rights-managed, non-duplicated visual assets. When the same photograph appears in two or more databases under different file names and metadata tags, the legal and licensing exposure can be significant. A single Getty Images or Shutterstock file, licensed once and inadvertently re-uploaded under a different file name, can generate a duplicate-use claim that costs a contracting organisation thousands of euros to resolve.

How the Duplication Problem Built Up

The roots of Milan's duplicate image problem stretch back to the mid-2000s, when the city's major institutions — the Comune di Milano, Fondazione Fiera Milano, and the various agencies managing urban regeneration in Porta Nuova and the Isola district — began digitising their assets independently, with no shared taxonomy or centralised repository. Each agency built its own content management system. Photographers working a single event might deliver files to three separate clients, each of which would upload the same image under a different naming convention.

The Porta Nuova development, which reshaped the skyline between Piazza Gae Aulenti and the Garibaldi–Repubblica axis through the 2010s, generated an enormous volume of architectural photography. That photography was used simultaneously by the developer Coima, by the Comune's urban planning communications office, and by individual tenants in the towers. The same aerial shot of the Bosco Verticale appeared in hundreds of separate asset folders across those organisations, with no mechanism flagging the redundancy.

By 2023, a report commissioned by the city's digital transformation directorate — referenced in a Comune di Milano council presentation that year — estimated that duplicate and near-duplicate image files accounted for roughly 34 percent of storage load across surveyed municipal platforms. Storage costs are not trivial at scale: enterprise-grade archival storage in European data centres ran at approximately €0.02 per gigabyte per month in 2024, meaning a multi-terabyte archive carrying a third of redundant files represents a measurable and recurring waste line.

What the Current Audit Covers

The current remediation effort, which began formally in January 2026 ahead of the Winter Olympics visibility push, is being coordinated across several fronts. The Milan-Cortina 2026 organising committee needed a clean, rights-verified image library for international press distribution. That requirement created a forcing function: for the first time, there was a hard deadline and a high-profile external audience that would expose sloppy metadata and duplicate files.

Institutions along the Via Tortona design corridor and in the Brera district — both of which produce dense volumes of event photography each April during Fuorisalone — are also participating in the audit. The goal is a unified digital asset management protocol that will apply consistent file-naming standards, embed licensing metadata at the point of upload, and use perceptual hashing software to flag near-identical images before they enter the archive.

For organisations managing visual assets in Milan — whether a studio on Via Savona, a fashion house with a headquarters near the Duomo, or a public body filing documentation for planning approvals — the practical advice is straightforward: conduct an internal duplicate audit before the city's new unified standards take effect. The Comune di Milano has signalled it expects participating institutions to have submitted compliance documentation by the end of the third quarter of 2026. Missing that window likely means a forced migration on someone else's timeline, which is always more expensive than doing it yourself.
