Riaucourt's 18th-century church has an elongated floor plan, with a single-vessel nave with a ceiling, preceded by a bell tower-porch. It has a 1-bay choir with a flat cross-vaulted chevet. The south chapel is rib-vaulted and was added in 1863 (date on the key). François Nicolas Lancret, an expert architect, drew up an estimate for rebuilding the church and presbytery on 19 November 1779. It was blessed in 1782 by Abbé Nancey.
