Among the many thermal riches for which Vichy is famous, the Célestins Spring holds a special place as a true natural treasure. It is a natural mineral spring whose water emerges through ancient aragonite rock. For centuries, France has carefully preserved this gem, turning it into a symbol of wellness and elegance.

The spring is protected by a magnificent pavilion built in the Neo-Louis XVI style at the turn of the 19th and 20th centuries. The water temperature here always remains constant — around 17.3–22 °C — and its unique composition includes 15 types of mineral salts. The landmark inherited its name from a 15th-century Celestine monastery, whose ruins still serve as a reminder of the location's rich past.
Today, Source des Célestins is not just a historical site, but also an active drinking hall within the Parc des Sources. "Célestins" water is recognized as a benchmark of French quality and is highly valued for its magnesium content, which helps with migraines and fatigue. It is an essential stop for anyone wishing to touch the living history of this world-renowned balneological center.
