Fontaine de Vaucluse



Geography
Fontaine-de-Vaucluse ("spring of Vaucluse") is built around a spring in a valley at the foot of the Vaucluse Mountains, between Saumane and Lagnes, not far from L'Isle-sur-la-Sorgue. It is named after the spring, the source of the River Sorgue.

Hydrography
The fountain, or spring, of Vaucluse, situated at the feet of a steep cliff 230 metres high, is the biggest spring in France. It is also the fifth largest in the world with an annual flow of 630 million cubic metres.

The fountain of Vaucluse surges in March for about 5 weeks and then subsides. The increased flow of water swells the Sorgue to flood. The mechanism behind the surging remains somewhat of a mystery.
