Le château en bref
Fort-Louis (Bas-Rhin) is a new fortified town designed by Vauban on an island in the Rhine, at a site with no bridge or crossing, to support the defence of Alsace against Strasbourg and Philippsburg. Construction took place from 1686 to 1690: Vauban laid out a town on an orthogonal plan, enclosed by a bastioned enceinte, with a square citadel at its centre. The Treaty of Ryswick (1697) obliged France to dismantle the horn-work on the right bank. A Prussian siege in 1793 largely destroyed the town; the enceinte and the fort were then, for the most part, demolished in the nineteenth century, while the Rhine was canalised and the river moved about one kilometre eastwards. Earthworks, ditches and sections of the citadel wall remain; the present village retains the orthogonal layout of Vauban's town.
