The Louvre Conservation Center, located in Liévin (20 miles or so southwest of Lille), “has six storage areas, including dry, low-humidity areas for metalworks, a photography studio, workshop rooms, a varnishing booth, and study space. The center has large windows for natural light, and the rooftop garden features 27 seed varieties. More than 5,000 plants have been sown around the building.” – Architectural Digest
