The world’s largest digital art gallery has opened in Bordeaux, France. Bassins de Lumières now sits on a former Nazi submarine base that was used to protect the German fleet from aerial attack while vessels were being fixed during World War II, and now projects large-scale images of works by the famed Austrian painter, Gustav Klimt.

The vast bunker spans 21 million cubic feet of reinforced concrete that can fill nearly 240 Olympic swimming pools and is also comprised of four parallel sections with walkways that allow visitors to explore roughly 130,000 square feet of immersive artwork powered by 90 video projectors, 80 speakers and over 60 miles of optical cables.

The Gustav Klimt: Gold and Color exhibition features portraits, landscapes, and nudes in the artist’s unmissable, gilded style. The show also chronicles Klimt’s career evolution, from his departure of the neoclassical to pioneering the Vienna Secession movement. A smaller section devoted to colorful abstract pieces by renowned German artist Paul Klee is also on display. Paul Klee: Painting Music pays tribute to the artist’s unknown musical abilities and immerses viewers “from an opera overture in an imaginary city to an underwater concerto amidst gold and multicolored fish,” as per the gallery’s statement.

Reservations to Bassins de Lumières are required by the attendees, as well as the agreement to precautionary health measures such as wearing masks, maintaining a distance of roughly three feet from other visitors as well as undergoing body temperature screenings.
