Saint-Gengoulf church is an elongated building. The six-bay, three-vessel nave is preceded by a bell tower crowned by a polygonal stone spire. Its upper storey houses an organ loft and its base is flanked by two chapels. The nave is followed by a choir consisting of a straight bay followed by a three-sided apse, all covered by a six-quarter rib vault. The sacristy is located against the south wall of the choir.
Saint-Gengoulf church was rebuilt in 1600. In July 1823, the contractor Minguet drew up plans to move the bell tower to the front of the nave. On 14 May 1859, the architect Henry Barbier drew up an estimate and plans to rebuild the church in the style of the first half of the 13th century. According to the estimate, the ribs were to be made from Bugnières stone, the vaults from tuff, the lime from Hortes, the sand from Rosoy, the foundations and plinth from Rosoy bluestone, the ashlar from Rosoy, the pillars and capitals from Grenant and the roofing from Angers slate. The work was completed in 1864 and, as Barbier had died, the architect Jules Girard was put in charge of the accounts and acceptance of the work. On 2 May 1865, Hannaire-Viard, an architect from Rosoy, was commissioned to draw up an estimate for finishing the bell tower, which was then raised to the ridge of the nave. The estimate, which was revised twice the following year, provided for the use of ashlar from the Chevillon quarries.
