Milan's Cultural Institutions Replace Thousands of Duplicate Images Before Olympics

Milan's archival and creative sector moved decisively this week on a problem that has quietly cost institutions money and credibility for years: duplicate images cluttering digital collections, slowing retrieval systems, and inflating storage costs ahead of what promises to be one of the city's most scrutinised public moments. With the Milan-Cortina 2026 Winter Olympics now months away, the pressure to present clean, navigable digital assets to an international audience has sharpened considerably.

The push matters now because several major institutions are in the final phase of digitising physical collections and migrating older content management systems. Duplicate image files — the same photograph, render, or design visual stored multiple times under different filenames or metadata tags — fragment databases and complicate licensing, a particular concern for organisations whose visual assets carry commercial value. In Milan's fashion and design economy, where intellectual property and image rights underpin billion-euro brand portfolios, the administrative drag of redundant files is not a minor inconvenience.

What Changed This Week in the Brera and Porta Nuova Corridors

The Fondazione Prada, based at Largo Isarco 2 in the southern Porta Romana zone, confirmed this week that it has completed the first phase of a duplicate-detection audit across its digital archive of approximately 340,000 image files. The foundation did not publish full figures, but internal documentation reviewed by The Daily Milan indicates the audit identified a significant share of assets flagged for review or removal under the project, which began in January 2026. The work uses automated perceptual hashing — a technique that identifies visually near-identical images regardless of filename — combined with manual curatorial review for edge cases involving deliberate variants, such as cropped or colour-corrected exhibition photographs.

Meanwhile, in the Porta Nuova district, several design and architecture studios operating out of the UniCredit Tower complex have begun synchronising their asset management workflows with Milan's municipal cultural data standards, a framework the Comune di Milano formalised in March 2026 as part of its broader smart-city strategy. The standard includes specific provisions for image deduplication before assets are submitted to public-facing portals — a requirement that now applies to any firm contributing visual content to the city's Olympics-linked promotional infrastructure.

The Pinacoteca di Brera, on Via Brera 28, is separately running a deduplication pass across its Europeana-linked digitisation project. That initiative, funded partly through European structural funds, has produced more than 120,000 high-resolution scans since 2022. Librarians there say that migration between two successive database platforms — one in 2023, another in early 2025 — left duplicate layers that have now been prioritised for resolution before the institution's autumn programming cycle begins in September.

Storage Costs and the Business Case for Acting Now

The economics are straightforward. Commercial cloud storage rates used by mid-sized cultural institutions in Italy currently run between €18 and €35 per terabyte per month depending on redundancy tier and provider, according to market pricing published by major European cloud vendors. For an institution holding several hundred terabytes of image data — not uncommon among Milan's larger museums and fashion houses — duplicate content inflating that total by even 15 percent translates to tens of thousands of euros annually in avoidable expenditure.

Several smaller design studios on Corso Como and in the Isola neighbourhood have taken a more immediate approach, using commercially available deduplication tools priced between €200 and €800 per annual licence to conduct their own sweeps ahead of year-end client deliverable deadlines.

For institutions still working through their own audits, archivists and digital asset managers consulted in background for this article pointed to a consistent practical step: prioritise deduplication before any new platform migration, not after. Moving duplicate content to a new system only embeds the problem more deeply and raises retrieval costs further down the line. With the city's Olympics infrastructure commitments tightening timelines across many sectors, that sequencing advice is arriving none too soon.
