Fosse Dionne, Natural spring in Tonnerre, France.
The Fosse Dionne spring releases 311 liters of water per second through a circular stone basin, creating a constant flow of turquoise water.
Dating back to 659 AD, the spring served as a water source for the Roman settlement of Tornodurum and later received an 18th-century washing house structure.
The spring holds connections to Celtic traditions, with its name derived from 'Divona,' meaning divine, and features in numerous local myths about serpents.
The site remains accessible every day throughout the year, though visitors should note the absence of wheelchair facilities and safety barriers around the water.
Multiple diving expeditions attempted to discover the source of the spring, reaching depths of 70 meters without finding its mysterious origin point.
