Origin and history

The Hailly d'Aigremont hotel, also known as the Ailly d'Aigremont hotel, is a private hotel located at 45 rue de Roubaix in Lille, in the Nord department. Built in 1703 for Pierre-Louis Jacobs d'Hailly, it embodies the Lille civil architecture of the early eighteenth century. Its organisation "between courtyard and garden" reflects the codes of the aristocratic mansions of the time, with a garden extending to Carnot Boulevard, once crossed by the Old Men's Canal. This hotel also illustrates the urban transformations of Lille, between medieval heritage (channels) and modernization.

Confiscated during the French Revolution, the hotel changed hands several times: sold to a manufacturer and then to a dye maker, it was then acquired by the nuns of Notre-Dame-du-Cenacle in the 19th century. The latter made changes before abandoning him during the separation of the Church and the State in 1905. In 1907, Jules Scrive-Loyer bought him back, then handed him over to the Army Department in 1946. Since then, it has been home to the Land Forces Command, mixing civil history and military function.

Ranked a historic monument since 7 December 1965 for its facades, roofs, and floors of the courtyard and park, the hotel bears witness to the social and political evolution of Lille. Its inscription protects both an architectural (classical Lille style) and a historical heritage, linked to the revolutionary, industrial, and religious upheavals of the region. The proximity of the Lille-Flandres station and its access via the metro underline its anchoring in the contemporary city.

Available sources, such as Christiane Lesage's (1980) or those led by General Pierre Coursier (1999), document his role in local history. The hotel remains a symbol of the interaction between civil, religious, and military power, while being a preserved example of Lille urban planning of the 17th and 18th centuries.
