The Saint-Sulpice church in Amettes, a sober building from the 16th century, is in late Gothic style and has retained beautiful ribbed windows in the nave. But it owes its current imposing appearance to the extension in the 19th century (1862-1864), which made it a coherent whole with the oldest part. This extension was made necessary by the influx of many pilgrims.
The village of Amettes and its church are indeed closely linked to the personality of Saint Benoît Joseph Labre, son of a farming family from the village. Thus, in the church we can find numerous testimonies of the life and death of the “Wanderer of God”, beatified in 1860 and canonized in 1881: the baptismal font on which he was baptized in 1748 or the historic altar of the church where he served mass; but also more personal memories of Benoît Joseph: objects that belonged to him and relics of this great pilgrim, poor among the poor, such as the sedan chair on which he died in Rome in 1783. The contemporary stained glass windows of the choir tell the life and expression of the spirituality of the holy pilgrim.
The church also preserves elegant furniture from the 18th century, as well as, in the right chapel, bas-reliefs around the Blessed Sacrament, works by the artist Jean Lambert-Rucky.
