The lands of Brégançon Castle were supplied with fresh water following the construction of a dam by the castle's owner, Hermann Sabran, at the end of the 19th century. This work, still visible today, benefited local farmers and allowed the development of agriculture on the lands of the estate. Polyculture was gradually abandoned in favor of vine and olive growing in the mid-1950s after the Second World War, marked by the occupation of the castle of Brégançon by the Italians and the Germans and its partial destruction.
