Milan Moves to Purge Duplicate Images from Its Digital Public Record — But Rivals Are Moving Faster

Milan's municipal digital archive contains tens of thousands of duplicate images — redundant photographs, scanned documents filed twice, and legacy visual assets stored across incompatible servers — and city administrators are now under pressure to clean house before the Milan-Cortina 2026 Winter Olympics put the city's digital infrastructure under unprecedented global scrutiny. The Comune di Milano has quietly begun a remediation process, but experts who track municipal data governance say the effort is behind schedule and under-resourced compared with what peer cities have done.

The issue matters now for a specific reason. With Olympic broadcast partners, international tourism platforms, and fashion-week media operations all drawing on Milan's official image libraries, duplicate and misclassified assets create real costs: storage overhead, licensing disputes, and, in some cases, the wrong photograph surfacing in official communications. The Porta Nuova district, whose skyline has become Milan's most-reproduced contemporary image, has been cited internally as a particular problem area, with multiple versions of the same aerial photograph catalogued under different metadata tags across at least three separate city-run systems.

What Milan Is Actually Doing

The Comune di Milano's digital services directorate launched a deduplication audit in January 2026, working alongside the publicly funded archive body Fondazione Giangiacomo Feltrinelli, which manages a significant share of the city's cultural image stock. The project is centred on the integration of two legacy content management systems that were never designed to speak to each other — one inherited from the pre-2011 administration, another introduced during the Expo 2015 preparation cycle. According to public procurement documents posted on the Comune's transparency portal, the contract for technical remediation was awarded in March 2026 at a value of approximately €340,000, covering both automated deduplication software licensing and manual review by a team based at the civic technology hub in via Larga.

The scope is substantial. The city's official image repository, accessible through the Archivio Fotografico del Comune di Milano near the Castello Sforzesco, holds an estimated 1.2 million catalogued assets, a figure that has grown sharply since 2015. Staff there have been tasked with flagging images duplicated across the Porta Nuova development authority's own picture library and the separate tourism-facing database maintained by Milano & Partners on via Dogana.

How Milan Compares with Amsterdam, Paris and Tokyo

Amsterdam completed a comparable deduplication exercise for its Stadsarchief — one of Europe's largest municipal archives — in 2023, deploying a machine-learning pipeline that cut redundant digital assets by roughly 34 percent across 800,000 records. Paris, ahead of the 2024 Summer Olympics, ran a six-month sprint through the Bibliothèque historique de la Ville de Paris that standardised image metadata across 14 departmental systems. Tokyo's metropolitan government began its own deduplication programme in 2022 and has since moved to a unified cloud-based DAM — digital asset management — platform, meaning new duplicates are flagged automatically at the point of upload rather than retrospectively.

Milan's January 2026 start date puts it roughly two to three years behind those benchmarks, and the €340,000 contract is modest by comparison: Amsterdam's 2023 project reportedly cost closer to €800,000 when staff time was included. The Lombardy regional government, which maintains its own parallel image systems and has an often-fractious relationship with Beppe Sala's centre-left city administration, has not yet announced any coordinating initiative, leaving open the question of whether regional and municipal archives will ever be rationalised into a single searchable system.

For businesses that depend on accurate official imagery — architecture firms in Brera, fashion houses operating out of the Quadrilatero della Moda, media outlets covering Milan-Cortina — the practical advice right now is straightforward: do not assume that an image pulled from any single city portal is the canonical, rights-cleared version. Cross-check against the Archivio Fotografico directly and confirm licensing status in writing. The deduplication project is scheduled for a first-phase completion by October 2026, two months before the Winter Olympics opening ceremony, but that deadline has already slipped once from the original August target.
