Not so much a terrace here as an upper deck, this arts centre has been afloat at the foot of the National Library (BNF) since 2010 when it joined the flotilla of cool riverboat venues moored in the 13th. And it’s been giving the Batofar (Paris’s stalwart floating nightclub) a run for its money, with an excellent line-up of concerts and art exhibitions. The coveted terrace doubles as a bar, restaurant and octopus gardener’s paradise, decked out with myriad aquatic plants. The venue regularly hosts live music in a range of genres, from minimalist Norweigan pop and indie folk to rock and jazz. It's eclectic enough to match Le Petit Bain’s architecture: designed by the Encore Heureux collective, it looks like a fluorescent green barge topped by a cubist wooden tree house.
