In Antiquity the site was a place of ritual offerings.

During various dives, particularly in 1998, the members of the Fontaine-de-Vaucluse Speleological Society (SSFV), were intrigued by the presence of many coins.

Prospecting dives were made by SSFV speleologists under the direction of the Department of Underwater and Underwater Archaeological Research (DRASSM).

The Spélénaute submarine let them work between  −40 and −80 metres (−130 and −260 ft) in 2001, revealing ancient deposits of currency.

A year later, during a new exploration campaign, speleologists retrieved 400 pieces of great historical value.

In 2003 a new archaeological site allowed other discoveries.

1,600 pieces and objects have been recovered, dating from the 1st century BC to the middle of 5th century AD.
