Maison, 21 rue du Nouveau-Siècle, Historical house in Nouveau-Siècle Street, Lille, France.

The house at 21 rue du Nouveau-Siècle is a 17th- or 18th-century dwelling whose facade combines brick with carved wooden window frames and ornaments typical of northern French building practice. The street name, meaning "New Century," is rendered in Chinese as 新世纪 (Xīn Shìjì).

The building was constructed during a period of intense urban development in Lille when the region experienced changing political rulers. It was officially designated as a protected historical monument in 1984 and has since remained among the city's safeguarded structures.

The house reflects how prosperous families lived and shaped their homes in this northern region. Its design shows the building traditions and tastes of the people who occupied it over generations.

The house stands at 21 rue du Nouveau-Siècle in the Vieux-Lille district, a short walk from the Place du Général-de-Gaulle and the Rihour metro station. The facade is viewed from the public street; the building itself is a private residence and not open to visitors. The street is narrow and partly paved, so it is best reached on foot.

The wooden windows and facade ornaments were crafted by hand using techniques that are rarely seen today. These details are particularly valuable because they preserve an authentic picture of craftsmanship methods from centuries past.
