The Bibliothèque et Villa Marmottan in Boulogne has reopened to the public, with access beginning on October 6, 2026. The site, a 19th-century building, was officially inaugurated on the evening of Wednesday, September 30, after five years of extensive renovation. The building had been closed since 2018 due to serious structural issues, including cracked floors, leaking windows, humidity, and even mushrooms growing on the walls. Adrien Goetz, the site’s director, told BFM that "No one imagines how bad the condition of the building was." The renovation, which cost 10 million euros, was carried out by the Académie des Beaux-Arts, the organization that owns the site. The Académie shared before-and-after photos on Instagram, showcasing the transformation of several restored spaces within the building. The Bibliothèque et Villa Marmottan will now serve as an artists’ residence, welcoming creators from around the world. Adrien Goetz explained that this initiative reflects "the very spirit of the Académie des Beaux-Arts (…) We are here to encourage young artists who are just starting out." The site has also announced a programming schedule for the 2026-2027 season, which will include concerts, masterclasses, and conferences until next June. The public will be able to explore the newly renovated building, named after its builder, Paul Marmottan. Paul Marmottan was a passionate collector and heir of the Napoleonic era, and he constructed the Bibliothèque et Villa Marmottan between 1890 and 1920. He built the structure to conduct research on the first half of the 19th century in Europe. After his death in 1932, the villa became a cultural hub and continued to function as a library, housing many treasures from the 19th century. The building’s revival aims to honor its historical significance while providing a space for artistic and academic engagement.
