A former foundry dating from 1835 that supplied iron for the French navy and railroads now houses Paris' first digital art museum, opened in 2018. The 1500-sq-metre La Halle mounts dazzling light projections that take over the bare walls. Long programs lasting around 30 minutes are based on historic artists' works; there's also a shorter contemporary program. Screenings are continuous. In the separate Le Studio space, you can discover emerging and established digital artists.
