A Saltern was a type of clayhut used for early salt production. The huts had a hole in the roof to allow smoke to escape. Large fires were lit beneath clay troughs of brine to evaporate water leaving salt crystals. Sea water would not have been used in salterns, but rather brine produced by passing fresh water over salt-rich sand collected from beneath the sea and packed into clay troughs.

The saltern was discovered at the bottom of a 17th century well situated in the center of a natural geological reserve in Haute-Provence near Moriez, a small village in the Alpes-de-Haute-Provence department.
An analysis of the pollen content in core samples of the sediment should enable the teams to refine the initial dates and provide greater insight into the climatic conditions that prevailed when salt harvesting first began in Europe.
This unusual discovery came about as a result of a joint saltern research program in the Alps region organized and sponsored by several institutions: the regional Midi-Pyrénées CNRS, PACA’s regional department of archeology, the DRAC PACA, and the geological reserve of Haute-Provence.
