Tours de Chignin, Medieval towers in Chignin, France.

Tours de Chignin is the remnant of a fortified camp whose seven towers stand on a plateau at Bourdeau, Montagny and Les Tours, 0.6 km west-northwest of the village church in Chignin, Savoie. The plateau reaches 420 m and is closed to the north by the Montronjoux and Mont-Saint-Michel hills. Two of the towers appear in the photograph: a square light-grey tower with a pointed dark roof and spire, and a taller pale tower with an uneven top, both rising above rows of vines.

Built in the 13th century, these towers arose after the lordship of Chignin was divided among several heirs, each establishing their own fortress. This period of division created what became a complex fortified settlement.

The Biguerne is a separate estate, not one of the towers: Saint Anthelm was born there in 1107, and the Chartreux rebuilt its ruined chapel in 1877 to designs by Pierre Bossan, architect of Fourvière. The commune bought the chapel and its surroundings in 2005.

The seven towers stand on a plateau at 420 m, 0.6 km west-northwest of the village church, in the hamlets of Bourdeau, Montagny and Les Tours. The site is reached on foot from Chignin; the plateau is bordered by the Montronjoux and Mont-Saint-Michel hills, separated by the Boisserette stream.

The site is called Les Tours, yet the sources record seven towers, not four, spread across the lieux-dits of Bourdeau, Montagny and Les Tours. The whole plateau was enclosed between 1233 and 1253 on the orders of Amédée V of Savoy during his war with the Dauphiné.
