Rue Mouffetard is a street in the 5th arrondissement of Paris, France.
Situated in the fifth arrondissement of Paris, Rue Mouffetard is one of Paris's oldest and liveliest neighbourhoods. These days the area has many restaurants, shops, and cafés, and a regular open market. It is centered on the Place de la Contrescarpe, at the junction of the rue Mouffetard and the rue de Lacepede.
The rue Mouffetard runs along a flank of the mont Sainte-Geneviève hill that was called "mont Cétarius" or "mont Cetardus" from Roman times; many historians consider "Mouffetard" to be a derivation of this early name.
The origins of this thoroughfare are ancient, dating back to Neolithic times. As with today's rue Galande, rue Lagrange, rue de la Montagne Sainte-Geneviève and rue Descartes, it was a Roman road running from the Roman Rive Gauche city south to Italy.
In 1910 Alexander Bogdanov delivered a lecture about Empiriomonism. Lenin replied quoting his own Materialism and Empiriocriticism in response. At the beginning of Chapter IV of The Sun Also Rises , Ernest Hemingway describes a taxicab heading down the Rue Mouffetard from the Place Contrescarpe.
