Église Saint-Martin de Hénin-Beaumont, Historical monument in Hénin-Beaumont, France.

Église Saint-Martin de Hénin-Beaumont is a Romano-Byzantine basilica-plan church with a concrete frame clad in reconstituted stone and grey slate roofs. Its cubic central block carries four 36-metre corner bell towers and an octagonal dome 26 metres across and 50 metres high, pierced by eight oculi and topped by a multi-branched cross. The nave and choir extend symmetrically west and east, ending in three-sided walls flanked by three-sided apsidioles.

A church stood on this site since the 12th century, but it was destroyed during World War I. The current building rose in 1929 according to architect Maurice Boutterin's design, replacing what had been lost.

The 36 windows were made by the Gaudin workshop, not Jean Gaudin alone; the two largest, north and south in the central block, show Saint Martin cutting his cloak for a beggar and Saint Vaast, patron of the Arras diocese. Inside, a Stations of the Cross by painter Henri Rapin and, in the Pietà chapel, a bas-relief by sculptor Gustave Crauk.

The church sits on Place Carnot in the town center and is easily reached on foot. Regular services take place here, and visitors can explore the building, though daylight hours are best for viewing the architectural details and windows.

The octagonal dome, 26 metres across and 50 metres high, is pierced by eight oculi and topped by a multi-branched cross. Four 36-metre bell towers stand at the corners of the cubic central block. The concrete frame is clad in reconstituted stone, with slate roofs.
