Église Saint-Majan de Villemagne-l'Argentière, Classified historical monument and church building in Villemagne-l'Argentière, France

The Église Saint-Majan de Villemagne-l'Argentière is a classified historical monument and church building located in the village of Villemagne-l'Argentière, in southern France. It has a single nave divided into three bays, ending in a polygonal choir surrounded by five small chapels, and is topped by a slate roof.

The abbey at Cogne appears in an 817 list of imperial monasteries; it was destroyed by the Saracens and restored under Charlemagne, first dedicated to Saint Martin. In 893 two monks stole Saint Majan's relics from Lombez and brought them here, adding the dedication. A 12th-century church with a defensive bell tower was rebuilt south in the 13th century; the seven-sided apse with five chapels followed a century later. Huguenots sacked the abbey in 1562, and the surviving two nave bays and apse were restored after 1663.

The dedication to Saint Majan dates from 893, when two monks, Sulsani and Centulle, stole the saint's relics from Lombez and brought them to the monastery at Cogne. Pilgrims on the Via Tolosana route to Santiago de Compostela came to venerate them. The church has served the parish since 1820, when the commune bought it after the Mare flood of 13 November 1818 damaged Saint-Grégoire.

The church stands in the village centre, but its floor was raised during the First Empire to protect it from floods of the Mare; excavations show the original ground lies 2.06 m below the present level. The building is closed to the west by a facade added after the 17th-century restoration, so the entrance is not the medieval doorway.

In 1373, with routiers besieging the town, the monks walled up the lower windows and built pointed arches carrying a crenellated parapet in front of a walkway between the buttresses. The floor was raised during the First Empire against floods of the Mare; excavations show the original level lies 2.06 m below today's.
