Fontaine de Vaucluse (spring) - a karst spring in the commune of Fontaine-de-Vaucluse, Vaucluse department. The largest spring in France by volume of water released, and ranks fifth among the world's largest springs. The spring, The fountain of Vaucluse, surges in March for about 5 weeks and then subsides. feeds the River Sorgue, is the only exit point of a 1,100-square-kilometre (420 sq mi) underground basin, which captures waters from Mont Ventoux, the Vaucluse Mountains, the Albion Plateau and the Lure Mountain.
In Antiquity the site was a place of ritual offerings. Various exploration dives revealed many ancient deposits of currency en historical objects. and a large collection dating from the 1st century BC to the middle of 5th century AD. The water of this exsurgence contains an average of 200 milligrams per litre (0.00012 oz/cu in) of calcium carbonate, and has an annual flow of about 700,000,000 cubic metres (2.5×1010 cu ft), so the reservoir loses 50,000 cubic metres (1,800,000 cu ft) of limestone each year.
This karstification phenomenon acting on the surface of the impluvium, removes an annual volume of 45 cubic metres (1,600 cu ft) per square kilometre, which disappears after being dissolved in the water.

Fontaine-de-Vaucluse - a small village around the Fontaine de Vaucluse, a spring in a valley at the foot of the Vaucluse Mountains. It is named after the spring, the source of the River Sorgue. The principal point of interest is the source of the Sorgue at the foot of a cliff 240 metres high, the subterranean basin of 1200 km2 feeding the source is -308m deep. It's a nice village to visit with the ruins of a castle, an ancient paper mill and a Resistance-, Petrarch- and Santon museum.
