Saint Lucien Church, Montgeroult

The Saint-Lucien church is a Catholic parish church located in Courcelles-sur-Viosne, in the Val-d'Oise, France. On the outside, the Romanesque bell tower from the second quarter of the 12th century is its most interesting feature. It remains from the first church, which must have been completed in 1161, the date of the parish's foundation, and was limited to a single vessel. The base of the bell tower has one of the oldest ribbed vaults in the department, and a dozen Romanesque capitals. The gothic choir of the beginning of the XIIIth century is very austere on the outside, but presents an elegant and neat architecture on the inside. It is one of the very few double-vessel choirs in the region, like Genainville. The southern vessel is located in the axis of the Romanesque nave and the bell tower. The other vessel, which has an additional bay to the north of the bell tower, is completed by a second nave soon after its construction. This nave, as well as the other one, is simply capped, and devoid of interest. However, the church of Saint-Lucien has the particularity of being a double nave church. It was classified as a historical monument by decree of October 14, 1908, and is now affiliated with the parish of Avernes et Marines, and Sunday masses are celebrated there irregularly, five times a year.
