Stanislas Belhomme announced the “temporary cessation of operation” of the Museum of Urban Art and Street Art Halle 07 (Mausa H07), in Saint-Chamond, near Saint-Étienne of which he is the founder. Installed in Hall 07 of the former Novaciéries steel factories, this 10,000 m² museum dedicated to street art closes just nine months after its inauguration.
The municipality inaugurated the Mausa H07 in May 2025. The establishment is part of a network already present in Neuf-Brisach (Alsace), Bitche (Moselle) and Toulouse-le-Château (Jura), opened in 2017. The equipment required around 10 million euros of public investment, including 1 million contributed by the entrepreneur Stanislas Belhomme. The rest comes from the European Union, the metropolis of Saint-Étienne and the city of Saint-Chamond. The museum aimed for between 120,000 and 150,000 visitors per year. International street artists, including Sickboy, Tarek Benaoum and Alex Senna, participated in the opening of the place, an industrial hall 200 meters long and 18 meters high.

However, attendance did not follow. In mid-December 2025, the site welcomed 7,600 visitors, including 2,740 in the first month, far from the announced objectives. As of January 31, the debt reached around 62,000 euros. Internal tensions have also weakened the structure. In September 2025, Stanislas Belhomme bought back the 60% of shares held by his partners, with whom he disagreed.
The founder claims to have “put everything (he) could put in this museum”but evokes a “debt accumulation” which led it to close “to stop the bleeding”. He now hopes for the opening of a safeguard procedure and calls on new patrons or investors to support the initiative. Without a rapid contribution of at least 100,000 euros, the future of the site is compromised.
The Mausa of Saint-Chamond is not an isolated case. A previous site in this network, located in Forges de Baudin (Jura), was placed in compulsory liquidation in 2019 after accumulating significant unpaid debts. In October 2018, the structure was ordered to pay 145,000 euros to the craftsmen who participated in the renovation of the site.
