Grand Casino de Vichy, Art nouveau casino in Vichy, France

The Grand Casino de Vichy is an art nouveau building in Vichy that houses a theater with seating for around 1,400 people. The main theater features a stage and continues to host performances and events, while gaming activities moved to an adjacent building in 1985.

The building opened in 1865 following a design by Charles Badger, after Napoleon III wanted to develop Vichy as an entertainment center. Its construction was part of a broader effort to transform Vichy into an elegant spa and cultural destination.

The theatre added in the early 20th century by Charles Le Cœur and Lucien Woog had a stage opening 12 metres by 15 metres, an orchestra pit and a hall of 1,400 seats. On 10 July 1940 the Chamber of Deputies and the Senate met in this theatre and voted full powers to Marshal Pétain. The building is now the Auditorium Eugénie, used for conferences and meetings within the Palais des Congrès complex.

The former Grand Casino building now serves as the Auditorium Eugénie, a conference and meeting hall within the Palais des Congrès complex, which also links to the adjoining opera house. Gaming moved to the neighbouring Grand Café in the early 1980s, so visitors looking for slot machines or tables should head there instead.

On 10 July 1940, the Grand Casino's theatre hosted the joint sitting of the Chamber of Deputies and the Senate that voted full powers to Marshal Pétain. The 1,400-seat hall, with its 12-by-15-metre stage and orchestra pit, thus witnessed the end of the Third Republic.
