The Église Saint-Omer is a church in Beussent, a commune in the Pas-de-Calais department in the Hauts-de-France region of northern France. The church is located on Rue De L'église in Beussent and is within a cemetery near the D127 road.
The Église Saint-Omer replaces an older building. This first sanctuary had some Romanesque elements. At the beginning of the 19th century, the original church consisted of two naves separated by three octagonal pillars. The removal of two of these supports, which obscured the view of the chancel, led to the collapse of the roof on May 12, 1873. Asked the next day by the works council, Clovis Normand found only a few standing walls when he removed the ruins on May 23 visited3.
The church has a Latin cruciform plan with an entrance on the western side. Built with local chalk and Creil stone, it combines formulas dear to Clovis Normand. A modillon cornice supports the roof as in Estrée and Neuville-sous-Montreuil. As often the tower precedes the nave, but here it is little raised. The upper storey, lit by twin windows on each face, directly supports the octagonal spire.
