This JEMA event features the opening of over fifty designer studios located under the historic brick arches of the Viaduc des Arts. Tracing its origins to the site was a 19th-century railway viaduct which was successfully rehabilitated in 1994 to serve as a hub for artistic trades. It represents the cultural identity of the 12th arrondissement as a district where industrial heritage meets contemporary luxury craftsmanship. Visitors can explore individual workshops to observe glass blowers jewelers and luthiers during live technical demonstrations. This gathering has a high social impact by providing a prestigious and public-facing workspace for the city’s finest artisans. For design researchers it serves as an invaluable archive of the evolution of artisanal manufacturing techniques in a metropolitan center. The event preserves the legacy of French savoir-faire by ensuring that rare manual skills are showcased and transmitted to a modern audience.
