Place Denfert-Rochereau, previously known as Place d'Enfer, is a public square located in the 14th arrondissement of Paris, France, in the Montparnasse district, at the intersection of the boulevards Raspail, Arago, and Saint-Jacques, and the avenues René Coty, Général Leclerc, and Denfert-Rochereau(fr), as well as the streets Froidevaux, Victor-Considérant and de Grancey. It is one the largest and most important squares on the left bank of the Seine.
The square is named after Pierre Denfert-Rochereau, the French commander who organized the defense at the siege of Belfort during the Franco-Prussian War (1870–1871). It is dominated by the Lion of Belfort statue (a smaller version of the original in the town of Belfort) by Frédéric Bartholdi.
