The fortress lies on the final promontory of mount Rachais, a narrow mountain that is the most southerly of the Chartreuse range. The location of the fort was chosen because it facilitated the surveillance and control of the city of Grenoble from the 19th century as well as the valleys of the Isère and the Drac, all the while being difficult to attack and overthrow because of the cliffs and steep ground by which it is surrounded.
