History and setting
L'Île Ô opened in January 2023 and presents itself as the first floating theater in Europe. It was designed by the Dutch architect Koen Olthuis of Waterstudio. A 450-tonne concrete hull, 38.33 meters long and 11.4 meters wide, carries a structure built entirely of wood under polygonal steel cladding. Voies Navigables de France granted the mooring in 2020 for 18 years. The building won the regional wood construction prize from Fibois in 2023. Day to day, the associative theater programs shows and workshops for children and families.
Getting there
The theater is ten minutes on foot from Lyon Perrache station (metro A). Tram T1 stops at Quai Claude Bernard, tram T2 at Centre Berthelot, and bus 34 at Pont Gallieni. A Vélo'v station is four minutes away, with bike racks on the riverbank.
