Eglise Notre Dame de Gernelle

The church of Notre-Dame must date back to the Middle Ages, probably to the 12th century, based on the shape of the bays in the south wall of the nave and the walled-up arcades on the north side (remains of a demolished or unbuilt aisle). The western portal seems to have been redone in the 19th century. The church of Notre-Dame, located in the centre of the village, has an elongated plan with a single-aisle nave. It is preceded by an entrance vestibule topped by a timber-framed bell tower. The choir, aligned with the nave, consists of a straight bay and a three-sided apse, with a sacristy attached to the north side.

The building is made of limestone rubble with a chain of Dom-le-Mesnil stone. The interior walls are rendered, and the floor is made of blue and purple slate tiles. The church has only one level: the north wall of the nave has walled arcades with rectangular bays, while the south wall has narrow lancet bays. The choir is lit by a large bay with tracery.

The interior volumes are covered by a false pointed barrel vault. The roofs are made of slate: the nave and the choir have a long-span roof, the apse a polygonal hip, the sacristy a lean-to roof, and the bell tower a polygonal spire.
