1. The Palais des Congrès - Opera
Jewel of the city’s architectural heritage, the Palais des Congrès – Opéra is made up of the former Grand Casino (which became the Palais des Congrès in 1995) and the Opéra, modernized by Jean Guilhem de Castelbajac. The original building (Casino-Theatre) was designed by the architect Charles Badger in 1865, at the request of Napoleon III, and included a ballroom, a theater, and gaming and pleasure rooms. But Vichy’s fame was such that in 1900, the architect Charles Lecœur was asked to enlarge the building to the west: the new Art Nouveau theater was the result with its 1,486 seats. The Opera House is the only Art Nouveau style theatre in gold and ivory colors in France.
