Church of Sainte-Austreberthe, Bours

The chapel Saint-Omer was built in 1230. In the 16th century, the body of the church was added, giving the buildings its current structure. The plan of the church is simple: a bell tower, a stone nave covered with a paneled vault, a choir, two chapels and a sacristy (seventeenth century). You can notice the cross vaulted transept ogives (sixteenth century) complex drawing.

St. Joseph's Church was built from 1913 to 1922 and was intended for the miners of pits no. 6, no. 6 bis and no. 6 ter, known as the Hallicourt pits. The works were interrupted by the beginning of the 1914-1918 war and only resumed after the war according to the plans of the architect Paul Degez. The neo-gothic brick church with corbelled stone corbels in the regional style has a bell tower above the façade, topped by a high slate spire and a pointed porch. It has a Latin cross plan.

The church of Saint-Éloi-et-Saint-Martin is a Gothic-style church whose construction began in 1523 on a former church whose 13th-century bell tower has survived. The church was sacked during the Revolution and its 16th century stained glass windows were destroyed. They were rebuilt identically in the second half of the 19th century. Closed from 2000 to 2009 because of its dilapidated state, the church was restored and in 2009 it received its additional dedication to Saint Eloi.
