Bâtiment des Forces Motrices, an opera house, is famous not only for its cultural events, but also its picturesque location. It is situated in the middle of the River Rhône. Constructed in the 19th Century, it was originally meant to be a water pumping and hydroelectric station. One can still spot two turbines in the lobby of the establishment. It has a capacity of about 950 seats and hosts ballet, theatre and musical performances. So come to watch the scintillating theatre plays, opera and concerts hosted here. Or simply step in to admire this stunning edifice.
