The Church of Saint Nicholas is a Catholic place of worship located in the commune of Mégevette in Haute-Savoie. The parish was formerly part of the Aulps Abbey. A first church, dating from the 10th century, was too small and dilapidated, and was replaced by the current one, which was built from 1872 to 1880. With its triple nave, it housed a thousand parishioners at the time. It is placed under the patronage of Saint Nicholas and Saint Theodule. Built in a style that blends "pseudo-Romanesque and Italian Renaissance," it is topped by an onion-domed bell tower. Beneath the church, a crypt—the Fernex family's funerary chapel—housed a 17th-century fresco, of which, unfortunately, almost nothing remains. Between 1975 and 1992, the church was completely restored.
