Positioned north of the capital, along the road that leads to the hilly villages, the massive square tower of Ecours castle is the only remnant of the 13th century construction, together with a short stretch of the ancient surrounding wall.
The building, which once belonged to the Lescours (De Curiis) family, among the most eminent of the Valdigne in the Middle Ages, was half enfeoffed to the nobles of Chatelard already in 1430. In 1551, the castle passed into the hands of the Bozel and subsequently, again in the 16th century, it became co-lordship of the Gal and the Malliet. In the following century, the fiefdom was reunited by the Passerins, who were still its owners in 1730.
