Fondazione Fiera Milano Historical Archive preserves the history of Milan’s fairgrounds and its fair through the documentation produced by the Fair Board ever since 1920, the year the first Milan Fair was held.
Its posters, photographs, newspapers, books, footage, and various documentary collections tell the many and various stories of all the exhibitor companies, visitors, sponsors, and workers at the fair.
All lined up, the documents surpass a kilometre in length. The major historical importance of the Archive has been formally recognized by the Soprintendenza of the Lombardy Region, as notified on February 1st, 2005.

Fondazione Fiera Milano is running a fully self-funded campaign to digitize and catalogue the documentary and photographic collections held by the Historical Archive. To date, more than twenty five thousand catalogue files can be accessed, for a total of forty thousand digital objects.

The Fondazione Fiera Milano Historical Archive is also the driving engine for the project PROSPETTIVA Archivi, promoted together with Afip International and La Triennale di Milano. The aim of the project is to preserve the archives of major Italian photographers and unlock access for the greater public to thousands of pictures, all digitized and catalogued according to international standards.
