Here's a not-to-be-missed opportunity for fans of unusual outings! On the occasion of the 40th Journées du Patrimoine, the former Babcock & Wilcox factories open their doors to you for free tours !




Located in the heart of La Courneuve, this industrial site with its monumental architecture is rarely open to the public. For the record, it was in 1898 that the French company Babcock et Wilcox was founded in Seine-Saint-Denis. In 1900, the Babcock boiler won the grand prize at the Exposition Universelle. In 1930, the company became France's leading manufacturer of industrial boilers. After many successful years, the site finally closed its doors in 2012.
Since then, the site has been taken over by numerous street artists and rehabilitated as a " Fabrique des cultures ", described as a unique living space drawing on the site's memory, and combining a major cultural and leisure facility with housing designed to meet new lifestyles. It is now a perfect example of the challenges of reconverting an industrial site.
For the Journées du Patrimoine 2025, come and discover the Babcock & Wilcox industrial site and its urban art trail free of charge. Two guides will be on hand to answer your questions.
Come and discover the missions and professions of the Banque de France de la Seine-Saint-Denis in the heart of the industrial heritage of the Babcock factories.
