Origin and history

The house of the Gros Chien is an architectural complex located in Sedan, in the Ardennes department, built in 1629 by Henri de Lambermont, master of forges. This complex, initially a military academy, was transformed into a linen factory by Denis Rousseau in 1688. The main building, rue du Ménil, features a two-storey facade with a gate decorated with canned pilasters and a broken pediment, while the attic is illuminated by three triangular windows. The date of construction, 1629, is visible thanks to the heads of metal draughts on the facade.

The first courtyard, known as the "Court of Heads", is distinguished by its mascarons carved on the lintels of the windows, supposed to represent Elizabeth de Nassau and her entourage. The buildings of this courtyard, made of cut stone, have a floor and attic with curved pediment windows. A second, more sober courtyard connects the interior spaces and opens onto the rue de Berchet. The materials are simpler, with stone-cut stone frames and bellows, reflecting a utility architecture.

Originally, the Gros-Chiens factory was a major competitor of Dijonval, another local textile factory. In 1823 Laurent Cunin-Gridaine bought and expanded the site, before it was called a "house" in 1842, marking the end of its industrial use. Ranked a historic monument in 1978, the building bears witness to the importance of the drapery industry in Sedan, a city marked by this activity from the 17th to the 19th century.

The protected elements include facades and roofs on Rue du Ménil and the first two courtyards, as well as the large wrought iron staircase. The exact address, 1 rue du Mesnil and 2-4 rue Berchet, confirms its anchoring in the historical center of Sedan, near the castle. The sources, such as the works of Gérard Gayot or Pierre Congar, underline his role in the Ardennes industrial heritage.

The factory, privileged in 1726, illustrates Sedan's economic development under the Old Regime. Its architecture combines careful decorations (steel in wrought iron, mascarons) and functional structures (indoor courtyards, stone buildings). Together, today preserved, offers a rare example of the transition between bourgeois habitat and textile production site, characteristic of the manufacturing cities of eastern France.

The site, open to visit under conditions, preserves traces of its industrial past, such as ground windows or stone frames. Its classification in 1978 preserved a heritage linked to the golden age of Sedan's sheets, whose reputation exceeded the borders of the kingdom. The cadastral archives and local studies, like those of Maya Bennani, document its architectural and social evolution.
