The glass and iron porch is similar to the designs of Hector Guimard for the Paris Metro. Each spoke ends in a musical clef note shape; ironwork by Emile Robert.

After the Second French Empire, the Belle Époque marked the second large construction campaign in Vichy. In 1903 the Opera House (l'Opéra), the Hall of Springs and a large bath designed in the eastern style were inaugurated. In the Opera, the parliament of the French Third Republic decided to grant full powers to Marshal Philippe Pétain, thereby terminating the republican regime and inaugurating Vichy France (July 10, 1940). Architect Charles Lecoeur was assisted by Lucien Woog. It has wonderful Art Nouveau décor, by sculptor Pierre Seguin, blacksmith Emile Robert and decorative painter Léon Rudnicki. The hall of 1450 seats was restored in 1995.
