The Montagne Sainte-Geneviève (Mons Lucotitius) is a hill overlooking the left Bank of the Seine in the 5th arrondissement of Paris. Atop the Montagne, are the Panthéon and the Bibliothèque Sainte-Geneviève, used by the students of the University of Paris (La Sorbonne). The side streets of the Montagne feature bars and restaurants, for example, in the Rue Mouffetard.
Moreover, the former campus of the École Polytechnique, located on the Montagne, now is the Ministry of Research. On the other side of the Montagne lie the rue d'Ulm and the École Normale Supérieure. Around AD 1110, the scholar and philosopher, Peter Abelard, established a school on the Montagne; twenty-six years later, Abelard returned, in the year 1136.
