Église Notre-Dame des Mineurs de Waziers, Catholic church in Waziers, France.

Notre-Dame-des-Mineurs is a 60-metre-long, 20-metre-wide brick church built by Louis-Marie and Louis-Stanislas Cordonnier, with a single bright nave carried on large concrete arches. Its truncated, crenellated bell tower ends in a slender spire, and the number three recurs throughout: three steps and three doors on the facade, three louvered colonnades on each tower face.

The building was constructed between 1923 and 1927 by architects Louis-Marie Cordonnier and his son Louis-Stanislas to serve Polish miners who had settled in the region. The project arose after World War One as a response to the needs of this growing population.

The number three recurs throughout the church: three steps lead to three facade doors topped by three tall windows, and each bell tower face has three louvered colonnades. This pattern refers to the Trinity and to the three mining settlements—Notre-Dame, la Clochette and Berce-Gayant—that the church serves.

The church stands in the centre of Waziers, in the Clochette district, and is best reached on foot from the surrounding streets. A celebration with presentation of the relic takes place on the 2nd of each month at 3 p.m. As the building remains in use for worship, visitors should time their visit around services.

The truncated crenellated bell tower topped with a thin spire has served as a notable landmark in the mining landscape for decades. This tower functions as a visual reference point for the three surrounding mining communities and creates a symbolic bridge between the church and the region's industrial past.
