History
Herbeumont Castle is a medieval fortress in Belgium, in the village of Herbeumont. Jehan de Rochefort built it after 1268, when Herbeumont became an independent lordship, making the castle the seat of his authority. Constructed in a single phase, it belonged to the tradition of the Philippian castle plan, a geometrically organized enclosure strengthened by projecting towers and a major keep.
From Lordship to Frontier Fortress
Before 1200, Herbeumont formed part of the lordship of Orgeo. It then belonged to the Walcourt-Rochefort family, and after two generations passed to Jehan de Rochefort. Four major families subsequently held the lordship: the Orjo family from 1268 to 1420, La Marck-Rochefort from 1420 to 1544, Stolberg from 1544 to 1574, and Löwenstein from 1574 to 1796.
From 1545, Herbeumont was incorporated into the Terres wallonnes, a western group of territories associated with the imperial principalities. The fortress consequently served as a frontier buffer between the Holy Roman Empire, a central European imperial polity, and the Kingdom of France. It also controlled a narrow point in the Semois valley, where routes ran parallel. One route led from Sedan through Bouillon and the Manhelles ford toward Neufchâteau, while another came from Carignan, formerly Yvois, by way of the Moulin ford.
Artillery, Siege, and Destruction
In the sixteenth century, the development of artillery required urgent changes to the fortress. The defenses were adapted with a gun platform, more sheltered towers, corner pavilions, and measures intended to resist attempts to undermine the walls. French troops commanded by the Duke of Nevers besieged Herbeumont for the first time in 1558.
The fortress was destroyed several times during the Thirty Years’ War, the European conflict fought from 1618 to 1648 through a mixture of religious and dynastic struggles. On 21 August 1657, troops commanded by the French marshal Henri de La Ferté-Senneterre captured the fortress and set it on fire. Troops of Louis XIV then dismantled it in the same year, and the site was abandoned in the middle of the seventeenth century.
Protection and Restoration
Protection of the ruins and their surroundings began in 1938, followed by separate protection of the ruins in 1989. Partial restoration started in 1994, and the ruins were renovated in 2010. Since 2009, the archaeological site has been listed as Exceptional Heritage of Wallonia.
Remains
Herbeumont Castle occupies a massive schist promontory, or tumulus, rising in the middle of the valley. Its steep sides overlook the Semois River by more than 100 metres and face the village of Herbeumont to the north. Because the rocky ridge was too steep for construction, its summit was levelled and widened into a plateau. The ruins now occupy the ridge above the isthmus of a long bend in the Semois known as the Tombeau du Chevalier.
Medieval Fortress
Enclosure and Towers
The original fortress followed a highland form of the Philippian plan. Its enclosure had an irregular trapezoidal layout with seven corner towers, comprising six round towers and a powerful quadrangular donjon. A donjon was the castle’s principal fortified tower, combining defensive and residential functions. Curtain walls, the connecting defensive walls between towers, linked the towers and donjon around a large central courtyard.
Approach and Defenses
The steep approach reinforced the defensive arrangement. The donjon and the towers surrounding the entrance made the fortress difficult to capture, while the enclosure formed a strong position above the Semois valley and its crossing routes.
Sixteenth-Century Defenses
Artillery Adaptations
Later defensive work responded to the changing force of artillery. A gun platform was added, and some towers were made more sheltered. Corner pavilions strengthened the defensive system, while further measures addressed attempts to undermine the walls.
