POP Plateforme Ouverte du Patrimoine Ministère de la Culture (France)

Overview

POP (Plateforme Ouverte du Patrimoine) is France's open heritage platform, operated by the French Ministry of Culture (Ministère de la Culture). It aggregates and provides free public access to several million records documenting French cultural heritage, including artworks, architectural monuments, photographs, illuminated manuscripts, and museum collections. As of 2025, the platform contains over 4.5 million records.

History and Founding

POP was launched in 2019 as a modernization project to replace the Ministry of Culture's legacy heritage databases, which had been developed and operated since the 1970s and 1990s. The project was conceived as a government digital startup (start-up d'État) supported by the Prime Minister's services under the beta.gouv.fr initiative. The development was carried out by the Atelier Numérique du Ministère de la Culture. A major overhaul of the platform was conducted between 2023 and 2025 to improve data production tools and the public interface.

Collections and Holdings

POP integrates several major legacy databases of the French Ministry of Culture: Joconde (the collective catalogue of collections of the Museums of France); Mérimée (architectural heritage, including listed and registered Historic Monuments and sites studied by regional inventory services); Palissy (movable heritage objects, including Historic Monuments and inventory items); Mémoire (photographic collections held by central and regional services of the Ministry of Culture); Muséofile (directory of approximately 1,200 institutions bearing the "Musée de France" designation); Enluminures (digital reproductions of illuminations from over 8,000 medieval manuscripts in approximately 100 French public libraries); and Rose-Valland (catalogue of artworks looted between 1933 and 1945). Together, these databases cover paintings, sculptures, architecture, photographs, objects, and illuminated manuscripts in both public and private ownership across France.

Access and Usage

All data on POP is freely accessible without registration. The platform supports open data reuse; the core databases (Joconde, Palissy, Mérimée, and Muséofile) are available as open data on data.culture.gouv.fr and data.gouv.fr. The platform's code is open source. POP supports IIIF (International Image Interoperability Framework) for image sharing. Several hundred French cultural institutions contribute data directly to the platform.
