Historical heritage of the Grésivaudan valley
A fortification of the 16th century and erected by Ecole Negro at the request of the first Duke of Savoy, Charles Emmanuel, Fort Barraux in the vicinity of Allevard-les-Bains owes its present shape to Vauban. Over the course of time it had undergone numerous modifications. As a true watchman of the Grésivaudan, it has taken on various missions as a deterrent against possible attacks and then as a military and civilian prison. During the 17th century, Fort Barraux in its original form was given a barracks and a chapel built on the site of the former renaissance chapel.
