Opéra des Nations, Genf

The Opéra des Nations – an all-wood temporary building – replaces the Geneva Grand Théâtre during its renovation from 2016 to 2018. The former Théâtre éphémère of the Comédie-Française has been transformed and adapted to opera, ballets and recitals: enlargement of the hall by 8 m, increasing the seat count to 1 118; addition of an orchestra pit; acoustic optimization with reflectors installed above the orchestra pit and on the sidewalls of the hall.
