Lyon's neoclassical 1831-built opera house was modernised in 1993 by renowned French architect Jean Nouvel, who added the striking semi-cylindrical glass-domed roof. On its northern side, boarders and bladers buzz around the fountains of place Louis Pradel, surveyed by the Homme de la Liberté (Man of Freedom) on roller skates, sculpted from scrap metal by Marseille-born César Baldaccini.
For drinks with a magnificent view, head up to the 7th-floor terrace bar Les Muses.
