Vichy is a city in the Allier department, Auvergne-Rhône-Alpes, central France, located in the historical province of Bourbonnais.
It is a spa and resort town and in World War II was the seat of government of Vichy France from 1940 to 1944. The term Vichyste indicated collaboration with the Vichy regime, often carrying a pejorative connotation.
In 2021, the town became part of the transnational UNESCO World Heritage Site under the name "Great Spa Towns of Europe" because of its famous baths and its architectural testimony to the popularity of spa towns in Europe from the 18th through 20th centuries.
