The Opéra Nouvel (Nouvel Opera House) in Lyon, is the home of the Opéra National de Lyon. The original opera house was re-designed by the distinguished French architect, Jean Nouvel between 1985 and 1993.
The city decided to build an opera house in 1985, within the shell of the existing 1831 building. The style of the house is essentially Italian with a horseshoe-shaped auditorium and tiers of boxes. Leaving only the existing foyer and the exterior façade, Nouvel tripled the space within the house by excavating below ground to create rehearsal space and, most strikingly, by doubling the height of the building by creating a steel and glass barrel vault which hid the fly tower as well as providing space for the ballet company.

Lyon (Liyon in Franco-Provençal or traditionally spelled Lyons in English) is the third-largest city of France. It is located at the confluence of the rivers Rhône and Saône, to the northwest of the French Alps and 243 miles (391 kilometers) southeast of Paris.
The City of Lyon has a population of roughly 522,000 in the 2020s within its small municipal territory of 19 square miles (48 square kilometers), but together with its suburbs and exurbs the Lyon metropolitan area has a population of 2,293,180, the second most populated in France. Lyon is the prefecture of the Auvergne-Rhône-Alpes region and seat of the Departmental Council of Rhône (whose jurisdiction, however, no longer extends over the Metropolis of Lyon since 2015).
The city is recognized for its cuisine and gastronomy, as well as historical and architectural landmarks. As such, the districts of Old Lyon, the Fourvière hill, the Presqu'île and the slopes of the Croix-Rousse are inscribed on the UNESCO World Heritage List as the "Historic Site of Lyon." Lyon was historically an important area for the production and weaving of silk.
