The Montagne Sainte-Geneviève
5e arrondissement · seven churches · 28 recorded visits

The fifth arrondissement climbs from the Seine to the hill named for Saint Geneviève, patron of Paris, then falls away to the south along the rue Mouffetard. Seven of its churches are in the record, as many as in any arrondissement; only the seventh matches it.
Between them they span much of the history of church building in Paris. Saint-Julien-le-Pauvre was begun in the twelfth century. Saint-Séverin, rebuilt in Flamboyant Gothic after the Hundred Years’ War, turns its ambulatory around a twisting pillar. Saint-Étienne-du-Mont keeps the only rood screen still standing in a Paris church. The Val-de-Grâce raises a dome painted by Pierre Mignard, and Saint-Nicolas-du-Chardonnet, completed in 1763, is classical in style.
Together the seven churches account for 28 of the 232 recorded visits, between October 2018 and October 2026.
