The current Sainte-Barbe church corresponds to the old pit of La Sentinelle and constitutes the oldest technical evidence of the mining basin. The pit was opened in 1818 but in 1824, the Cie d'Anzin built a new building, in brick, intended to house a steam engine. The building is built according to an elongated plan in order to move the extraction machine away from the well, located at the entrance of the church, and originally surmounted by the roller machine. The building that houses the choir housed the steam engine. The activity of the pit stops in 1830 and the Compagnie des Mines d'Anzin transforms it into a church between 1854 and 1872. Listed as a Historic Monument
