In 1204, on the occasion of a peace treaty with William IV of Forcalquier, Lansac was given to Rostang de Sabran. 30 years later, he left the place as a security to the Templars, who turned it into significant headquarters until the order's fall. Lansac came back in the family in 1816 and today Éléonore de Sabran - Pontevès goes on giving life to this site full of history.
The house of Sabran, one of the most ancient and well-known of Provence, originated in Languedoc, where it used to hold much of the seigniory of Uzès and the barony of Sabran. Earls of Provence in the 13th century, the Sabrans settled in this region where they owned among others the barony of Ansouis, as well as the principalities of Apt, Orange and Forcalquier. Thus they ruled from Naples to Narbonne.
By that time, the Sabrans also allied with the greatest courts of Europe with the four daughters of Raymond Bérenger IV: Marguerite of Provence married Saint Louis - king of France, Sancie became queen of Austria and empress of Germany, Béatrix queen of Italy, Naples and Sicilia, and Éléonore queen of England by wedding Henri III of Plantagenêt.
