The Permanence du Fer à Moulin is located at 2 rue du fer à moulin in the 5th arrondissement in the immediate vicinity of the Paris Mosque and the Jardin des Plantes. This southern part of the 5th arrondissement is peaceful, conducive to meditative walks, as opposed to the more lively streets of the Sainte Geneviève mountain or the rue Mouffetard.
