History
Huningue Fortress in France was built for the French monarchy between 1679 and 1691 according to plans by the military engineer Sébastien Le Prestre de Vauban. Designed in Vauban’s system of angular bastions, outworks, and layered artillery defenses, it became an important French position on the Rhine and a gateway for armies entering the Holy Roman Empire, a loose association of central European territories that lasted until 1806.
French Expansion on the Rhine
Huningue had long been contested by Basel and the Habsburgs, changing allegiance several times before Alsace was transferred to France by the Peace of Westphalia. The French monarchy then sought to secure its new Rhine territories. Although War Minister Louvois denied on 4 June 1679 that a fortress was planned, stone was already being procured. Vauban inspected the proposed site on 2 August, and earthworks began on 11 October.
Jacques Tarade directed the construction as chief engineer, while Roger Brulart de Puysieux became the fortress’s first governor. The foundation stone was laid on 19 March 1680. Louvois and Vauban gave the project high priority despite diplomatic opposition from Switzerland and Austria. Louis XIV visited on 15 October 1681. The principal works were finished in 1683, and the entire fortress was completed in 1691.
Construction transformed the local landscape. The fishing village of Gross-Hüningen was removed to make way for the fortress. By royal decree, its inhabitants were moved in 1684 to a new settlement several kilometres downriver on the Rhine island of Aoust, later known as Village-Neuf. The old village was completely demolished in 1687.
Schuster Island and the Rhine Frontier
In 1694, France added an outwork on Schuster Island and linked it to the fortress with a permanent bridge over the Rhine. Part of the island belonged to Basel, so the new position directly bordered Basel territory. Disputes over territorial and usage rights on the river and island later intensified into the Basel-French salmon-fishing dispute of 1736 and 1737.
The Peace of Rijswijk in 1697 required France to demolish the right-bank bridgehead, the works on Schuster Island, and the permanent bridge, returning the land and buildings there to the House of Baden. The demolition was incomplete, and France rebuilt the island fortifications during the War of the Spanish Succession, the European conflict of 1701 to 1714 over the succession to the Spanish throne.
In 1702, Louis XIV ordered General Villars to cross the Rhine at Huningue in order to draw Imperial troops away from the siege of Landau and join Bavarian allies. Villars reached Huningue between 28 and 30 September, after Landau had fallen. He placed 2,000 men in the ruins on Schuster Island and established a bridge of boats. On 1 and 2 October, French troops forced a bridgehead onto the German bank against Imperial forces commanded by Count Egon von Fürstenberg. Artillery exchanges continued until the French infantry was defeated at the Battle of Friedlingen on 14 October. The survivors withdrew into Huningue Fortress under cavalry protection.
During the War of the Austrian Succession, a conflict fought mainly from 1740 to 1748 over competing dynastic claims, Louis XV had a bridge of boats built at Huningue in 1741. It was replaced by a permanent Rhine bridge in 1746, but the Peace of Aix-la-Chapelle in 1748 required its removal.
Revolutionary and Napoleonic Wars
On 17 September 1793, Austrian troops stopped the French Revolutionary Army from crossing the Rhine in the engagement at Huningue. In December 1795, Marie Thérèse Charlotte de Bourbon, daughter of the executed Louis XVI, spent two nights at the Zum Raben inn inside the fortress. She was exchanged near Basel on 26 December for several French prisoners, including Armand Gaston Camus, Pierre Riel de Beurnonville, Jean-Baptiste Drouet, Hugues-Bernard Maret, Nicolas Marie Quinette, and Charles Louis Huguet, and was taken to Vienna.
The first siege began at the end of 1796 after the Battle of Schliengen. Austrian forces under Karl Aloys zu Fürstenberg attacked the French bridgehead on 30 November, but the assault was repulsed and the French commander, General Abbatucci, was mortally wounded. Following the fall of the French bridgehead at Kehl on 10 January 1797, Austrian heavy artillery was moved to Huningue. General François Marie Dufour capitulated on 1 February and surrendered the bridgehead on 5 February. The bridgehead was then demolished, after fighting and siege works had caused heavy losses on both sides.
The Sieges of 1813 to 1815
After Allied armies crossed the Rhine at Basel, troops under the Bavarian General Carl Philipp von Wrede surrounded Huningue Fortress on 22 December 1813. Colonel Jean Chancel commanded approximately 3,600 soldiers and 800 civilians inside. Wrede later moved most of his corps and artillery across the Vosges, leaving 2,500 men under Karl Baron von Zoller to continue the siege.
On 5 April 1814, artillery destroyed the outwork containing the machicolation tower and its surrounding redoubt. The southern hornwork was then shelled and stormed. Artillery fighting from 6 to 10 April was interrupted by a truce, followed by a heavy bombardment on 11 and 12 April from 106 guns. The fortress was damaged, and Allied troops entered on 16 April under a truce agreement. They occupied it jointly with the French, in the presence of the Russian Grand Dukes Nicholas and Michael. Bavarian troops withdrew on 8 June, leaving the fortress to the French under Colonel Jean Chancel.
When Napoleon returned from Elba on 1 March 1815 during the Hundred Days, the period of his return and renewed rule in France, the Huningue garrison declared for him. The defenses were reinforced, Joseph Barbanègre assumed overall command on 15 May, and Jean Hugues Chancel remained fortress commandant. On 11 June, soldiers and civilians were forbidden to communicate with Basel.
After Napoleon’s defeat at Waterloo on 18 June and his second abdication on 22 June, Austrian troops under Archduke Ferdinand crossed the Rhine at Basel on 26 June with approximately 130,000 men. Austrian and Swiss forces surrounded Huningue after fighting near Burgfelden. The fortress artillery shelled the Basel districts of St. Johann and St. Peter after Austrian troops had set fire to houses in several Alsatian communities.
Barbanègre rejected surrender demands on 3, 11, and 20 July. The garrison, initially about 2,000 strong, lost 385 men through desertion by 7 July and continued to shrink. An armistice concluded by Generals Claude-Jacques Lecourbe and Jean Rapp on 22 July included the fortress, although Huningue artillery shelled Basel again on 26 July. Swiss heavy artillery arrived by 15 July, Swiss sharpshooters entered the fighting on 6 August, and the Swiss Diet authorized the active deployment of 5,000 troops near Basel on 17 August.
The besieging force eventually comprised about 12,000 Austrians and 5,000 Swiss, supported by 110 guns, howitzers, and mortars. The fortress held approximately 2,400 men and 100 guns. The attack began during the night of 17 to 18 August 1815. After renewed bombardment and negotiations, Barbanègre signed the capitulation on 26 August, surrendering the fortress and its weapons in exchange for an honorable withdrawal by the garrison.
Demolition and Archaeological Investigation
The Treaty of Paris, concluded on 20 November 1815 under Swiss pressure, required the demolition of Huningue Fortress and prohibited France from rebuilding it or constructing new fortifications within three French leagues of Basel. Destruction had already begun on 31 August with the leveling of the Abatucci Redoubt and the lunettes. Demolition of the main fortress began on 17 October 1815 and ended on 15 January 1816. Approximately 10,000 people may have worked on the operation, including Swiss civilians, Sundgau farmers, and military miners. The resulting rubble was removed by May 1817.
Since 1938, the facade, bell tower, and roof of the former garrison church have been protected as a French historic monument. Archaeological excavations carried out in spring 2023 for planned new construction investigated remains of the southern hornwork and revealed underground passages not shown on the fortress plans.
Remains
The fortress was arranged as a pentagon with five bastions, a projecting angular form that allowed defenders to fire along the faces of adjoining walls. Curtain walls, the rampart sections between bastions, enclosed the central position. A broad water-filled ditch supplied by the Rhine surrounded the main rampart, while hornworks, outer defenses formed by two projecting arms and a connecting front, stood to the north and south.
Fortifications and Military Buildings
Advanced Works
Each curtain wall had a projecting tenaille, a low defensive work placed in the ditch, protected in turn by a lunette, a detached outwork. On the side facing Basel, a machicolation tower and a star-shaped redoubt strengthened the advanced defenses. The outwork containing the tower and its surrounding redoubt was destroyed by artillery on 5 April 1814. The Abatucci Redoubt and the lunettes were among the works leveled during the demolition that began in 1815.
Schuster Island Position
The advanced position on Schuster Island was connected to the fortress by a permanent Rhine bridge after 1694. Its fortifications were demolished under the Peace of Rijswijk, then rebuilt during the War of the Spanish Succession. The island’s military role was demonstrated during Villars’s 1702 campaign, when French troops occupied its ruins and used a bridge of boats to support the crossing toward the German bank.
Fortress Interior
The fortress mounted 140 cannon and included barracks for 5,000 men. Accommodation within the fortified area housed 1,200 inhabitants, alongside a church, hospital, arsenal, and military administrative buildings. Several buildings that stood inside the defenses survive, including one that houses the Musée historique et militaire and contains a large model of the fortress.
Garrison Church and Archaeological Remains
Former Garrison Church
The former garrison church at Place Abbatucci was built according to plans by Jacques Tarade. It has since been secularized and is valued as a concert venue for its room acoustics. Its facade, bell tower, and roof have held French historic-monument protection since 1938.
Southern Hornwork and Underground Passages
Archaeological work in spring 2023 exposed remains of the southern hornwork. The excavation also revealed underground passages that were not included on the fortress plans, adding physical evidence to the surviving understanding of the demolished defenses.
